+<para>This parameter has a structured value. It is a table of space-delimited
+path/value pairs. Each path identifies some element in the source document
+using a restricted subset of XPath (only the implicit child axis, no wildcards,
+no predicates). Paths can be either relative or absolute.</para>
+
+<para>When processing a particular element, the stylesheets consult this table to
+determine if a ToC (or LoT(s)) should be generated.</para>
+
+<para>For example, consider the entry:</para>
+
+<screen>book toc,figure</screen>
+
+<para>This indicates that whenever a <tag>book</tag> is formatted, a
+Table Of Contents and a List of Figures should be generated. Similarly,</para>
+
+<screen>/chapter toc</screen>
+
+<para>indicates that whenever a document <emphasis>that has a root
+of</emphasis> <tag>chapter</tag> is formatted, a Table of
+Contents should be generated. The entry <literal>chapter</literal> would match
+all chapters, but <literal>/chapter</literal> matches only <tag>chapter</tag>
+document elements.</para>
+
+<para>Generally, the longest match wins. So, for example, if you want to distinguish
+articles in books from articles in parts, you could use these two entries:</para>
+
+<screen>book/article toc,figure
+part/article toc</screen>
+
+<para>Note that an article in a part can never match a <literal>book/article</literal>,
+so if you want nothing to be generated for articles in parts, you can simply leave
+that rule out.</para>
+
+<para>If you want to leave the rule in, to make it explicit that you're turning
+something off, use the value <quote>nop</quote>. For example, the following
+entry disables ToCs and LoTs for articles:</para>
+
+<screen>article nop</screen>
+
+<para>Do not simply leave the word <quote>article</quote> in the file
+without a matching value. That'd be just begging the silly little
+path/value parser to get confused.</para>
+
+<para>Section ToCs are further controlled by the
+<parameter>generate.section.toc.level</parameter> parameter.
+For a given section level to have a ToC, it must have both an entry in
+<parameter>generate.toc</parameter> and be within the range enabled by

+<para>This parameter lets you select which method to use for sorting and grouping
+ index entries in an index.
+Indexes in Latin-based languages that have accented characters typically
+sort together accented words and unaccented words.
+Thus <quote>&#193;</quote> (U+00C1 LATIN CAPITAL LETTER A WITH ACUTE) would sort together
+with <quote>A</quote> (U+0041 LATIN CAPITAL LETTER A), so both would appear in the <quote>A</quote>
+section of the index.
+Languages using other alphabets (such as Russian, which is written in the Cyrillic alphabet)
+and languages using ideographic chararacters (such as Japanese)
+require grouping specific to the languages and alphabets.
+</para>
+
+<para>The default indexing method is limited.
+It can group accented characters in Latin-based languages only.
+It cannot handle non-Latin alphabets or ideographic languages.
+The other indexing methods require extensions of one type or
+another, and do not work with
+all XSLT processors, which is why they are not used by default.</para>
+
+<para>The three choices for indexing method are:</para>
+<variablelist>
+<varlistentry>
+<term><literal>basic</literal></term>
+<listitem>
+<para>
+(default) Sort and groups words based only on the Latin alphabet.
+Words with accented Latin letters will group and sort with
+their respective primary letter, but
+words in non-Latin alphabets will be
+put in the <quote>Symbols</quote> section of the index.
+</para>
+</listitem>
+</varlistentry>
+<varlistentry>
+<term><literal>kosek</literal></term>
+<listitem>
+<para>
+This method sorts and groups words based on letter groups configured in
+the DocBook locale file for the given language.
+See, for example, the French locale file <filename>common/fr.xml</filename>.
+This method requires that the XSLT processor
+supports the EXSLT extensions (most do).
+It also requires support for using
+user-defined functions in xsl:key (xsltproc does not).
+</para>
+<para>This method is suitable for any language for which you can
+list all the individual characters that should appear
+in each letter group in an index.
+It is probably not practical to use it for ideographic languages
+such as Chinese that have hundreds or thousands of characters.
+</para>
+
+<para>To use the kosek method, you must:</para>

+This method uses extensions to the Saxon processor to implement
+sophisticated indexing processes. It uses its own
+configuration file, which can include information for any number of
+languages. Each language's configuration can group
+words using one of two processes. In the
+enumerated process similar to that used in the kosek method,
+you indicate the groupings character-by-character.
+In the between-key process, you specify the
+break-points in the sort order that should start a new group.
+The latter configuration is useful for ideographic languages
+such as Chinese, Japanese, and Korean.
+You can also define your own collation algorithms and how you
+want mixed Latin-alphabet words sorted.</para>

+
+<para>The file is a well-formed XML file that

+The stylesheets ship with the default file. You can substitute

+
+<para>If <parameter>docbook.css.source</parameter> is not blank,
+and <parameter>make.clean.html</parameter> is nonzero, then
+the stylesheet takes the following actions:</para>
+
+<orderedlist>

+ <para>The stylesheet uses the XSLT <literal>document()</literal>

+ For example:</para>

+ </programlisting>
+ <para>However, if the <parameter>docbook.css.link</parameter>

+<para>If the <parameter>make.clean.html</parameter> parameter is nonzero

+and if the <parameter>docbook.css.source</parameter> parameter
+is not blank (the default is not blank),
+then the stylesheet will also generate a default CSS file
+and add a <tag>link</tag> tag to reference it.
+The <tag>link</tag> to the custom CSS comes after the
+<tag>link</tag> to the default, so it should cascade properly
+in most browsers.
+If you do not want two <tag>link</tag> tags, and
+instead want your custom CSS to import the default generated
+CSS file, then do the following:
+</para>
+
+<orderedlist>
+ <listitem>
+ <para>Add a line like the following to your custom CSS source file:</para>
+ <programlisting>@import url("docbook.css")
+ </programlisting>
+ </listitem>
+ <listitem>
+ <para>Set the <parameter>docbook.css.link</parameter> parameter
+ to zero. This will omit the <tag>link</tag> tag
+ that references the default CSS file.</para>
+ </listitem>
+</orderedlist>
+
+<para>If you set <parameter>make.clean.html</parameter> to nonzero but
+you do not want the default CSS generated, then also set
+the <parameter>docbook.css.source</parameter> parameter to blank.
+Then no default CSS will be generated, and so
+all CSS styles must come from your custom CSS file.</para>
+

+<para>When cross reference data is collected for resolving olinks, it
+may be necessary to prepend a base URI to each target's href. This
+parameter lets you set that base URI when cross reference data is
+collected. This feature is needed when you want to link to a document
+that is processed without chunking. The output filename for such a
+document is not known to the XSL stylesheet; the only target
+information consists of fragment identifiers such as
+<literal>#idref</literal>. To enable the resolution of olinks between
+documents, you should pass the name of the HTML output file as the
+value of this parameter. Then the hrefs recorded in the cross
+reference data collection look like
+<literal>outfile.html#idref</literal>, which can be reached as links
+from other documents.</para>

+<para>When cross reference data is collected for use by olinks, the data for each potential target includes one field containing a completely assembled cross reference string, as if it were an xref generated in that document. Other fields record the separate title, number, and element name of each target. When an olink is formed to a target from another document, the olink resolves to that preassembled string by default. If the <parameter>use.local.olink.style</parameter> parameter is set to non-zero, then instead the cross
+reference string is formed again from the target title, number, and
+element name, using the stylesheet processing the targeting document.
+Then olinks will match the xref style in the targeting document
+rather than in the target document. If both documents are processed
+with the same stylesheet, then the results will be the same.</para>

+<para>When olinks between documents are resolved for HTML output, the stylesheet can compute the relative path between the current document and the target document. The stylesheet needs to know the <literal>targetdoc</literal> identifiers for both documents, as they appear in the <parameter>target.database.document</parameter> database file. This parameter passes to the stylesheet
+the targetdoc identifier of the current document, since that
+identifier does not appear in the document itself. </para>

If an olink's <literal>targetdoc</literal> id differs from the <literal>current.docid</literal>, then the stylesheet can append the target document's title to the generated olink text. That identifies to the reader that the link is to a different document, not the current document. See also <parameter>olink.doctitle</parameter> to enable that feature.</para>

+<para>This parameter defines a list of lang values
+to search among to resolve olinks.
+</para>
+
+<para>Normally an olink tries to resolve to a document in the same
+language as the olink itself. The language of an olink
+is determined by its nearest ancestor element with a
+<tag class="attribute">lang</tag> attribute, otherwise the
+value of the <parameter>l10n.gentext.default.lang</parameter>
+parameter.
+</para>
+
+<para>An olink database can contain target data for the same
+document in multiple languages. Each set of data has the
+same value for the <tag>targetdoc</tag> attribute in
+the <tag>document</tag> element in the database, but with a
+different <tag>lang</tag> attribute value.
+</para>
+
+<para>When an olink is being resolved, the target is first
+sought in the document with the same language as the olink.
+If no match is found there, then this parameter is consulted
+for additional languages to try.</para>
+
+<para>The <parameter>olink.lang.fallback.sequence</parameter>
+must be a whitespace separated list of lang values to
+try. The first one with a match in the olink database is used.
+The default value is empty.</para>
+
+<para>For example, a document might be written in German
+and contain an olink with
+<literal>targetdoc="adminguide"</literal>.
+When the document is processed, the processor
+first looks for a target dataset in the
+olink database starting with:</para>
+
+<literallayout><literal>&lt;document targetdoc="adminguide" lang="de"&gt;</literal>.
+</literallayout>
+
+<para>If there is no such element, then the
+<parameter>olink.lang.fallback.sequence</parameter>
+parameter is consulted.
+If its value is, for example, <quote>fr en</quote>, then the processor next
+looks for <literal>targetdoc="adminguide" lang="fr"</literal>, and
+then for <literal>targetdoc="adminguide" lang="en"</literal>.
+If there is still no match, it looks for
+<literal>targetdoc="adminguide"</literal> with no
+lang attribute.
+</para>
+
+<para>This parameter is useful when a set of documents is only
+partially translated, or is in the process of being translated.
+If a target of an olink has not yet been translated, then this
+parameter permits the processor to look for the document in
+other languages. This assumes the reader would rather have
+a link to a document in a different language than to have
+a broken link.

+</para>
+
+<para>If <parameter>insert.olink.pdf.frag</parameter> is set
+to a non-zero value, then any olink targeting a
+PDF file will have the fragment identifier appended to the URI.
+The URI is formed by concatenating the value of the
+<parameter>olink.base.uri</parameter> parameter, the
+value of the <tag class="attribute">baseuri</tag>
+attribute from the <tag class="element">document</tag>

+In order to resolve olinks efficiently, the stylesheets can
+generate an external data file containing information about
+all potential cross reference endpoints in a document.
+This parameter determines whether the collection process is run when the document is processed by the stylesheet. The default value is <literal>no</literal>, which means the data file is not generated during processing. The other choices are <literal>yes</literal>, which means the data file is created and the document is processed for output, and <literal>only</literal>, which means the data file is created but the document is not processed for output.

+<para>Glossaries maintained independently across a set of documents
+are likely to become inconsistent unless considerable effort is
+expended to keep them in sync. It makes much more sense, usually, to
+store all of the glossary entries in a single place and simply
+<quote>extract</quote> the ones you need in each document.</para>
+
+<para>That's the purpose of the
+<parameter>glossary.collection</parameter> parameter. To setup a global
+glossary <quote>database</quote>, follow these steps:</para>
+
+<refsection><info><title>Setting Up the Glossary Database</title></info>
+
+<para>First, create a stand-alone glossary document that contains all of
+the entries that you wish to reference. Make sure that each glossary
+entry has an ID.</para>
+
+<para>Here's an example glossary:</para>
+
+<informalexample>
+<programlisting>
+&lt;?xml version="1.0" encoding="utf-8"?&gt;
+&lt;!DOCTYPE glossary
+ PUBLIC "-//OASIS//DTD DocBook XML V4.1.2//EN"
+ "http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd"&gt;

+&lt;title&gt;Jargon File 4.2.3 (abridged)&lt;/title&gt;
+&lt;releaseinfo&gt;Just some test data&lt;/releaseinfo&gt;
+&lt;/glossaryinfo&gt;
+
+&lt;glossdiv&gt;&lt;title&gt;0&lt;/title&gt;
+
+&lt;glossentry&gt;
+&lt;glossterm&gt;0&lt;/glossterm&gt;
+&lt;glossdef&gt;
+&lt;para&gt;Numeric zero, as opposed to the letter `O' (the 15th letter of
+the English alphabet). In their unmodified forms they look a lot
+alike, and various kluges invented to make them visually distinct have
+compounded the confusion. If your zero is center-dotted and letter-O
+is not, or if letter-O looks almost rectangular but zero looks more
+like an American football stood on end (or the reverse), you're
+probably looking at a modern character display (though the dotted zero
+seems to have originated as an option on IBM 3270 controllers). If
+your zero is slashed but letter-O is not, you're probably looking at
+an old-style ASCII graphic set descended from the default typewheel on
+the venerable ASR-33 Teletype (Scandinavians, for whom /O is a letter,
+curse this arrangement). (Interestingly, the slashed zero long
+predates computers; Florian Cajori's monumental "A History of
+Mathematical Notations" notes that it was used in the twelfth and
+thirteenth centuries.) If letter-O has a slash across it and the zero
+does not, your display is tuned for a very old convention used at IBM
+and a few other early mainframe makers (Scandinavians curse &lt;emphasis&gt;this&lt;/emphasis&gt;
+arrangement even more, because it means two of their letters collide).
+Some Burroughs/Unisys equipment displays a zero with a &lt;emphasis&gt;reversed&lt;/emphasis&gt;
+slash. Old CDC computers rendered letter O as an unbroken oval and 0
+as an oval broken at upper right and lower left. And yet another
+convention common on early line printers left zero unornamented but
+added a tail or hook to the letter-O so that it resembled an inverted
+Q or cursive capital letter-O (this was endorsed by a draft ANSI
+standard for how to draw ASCII characters, but the final standard
+changed the distinguisher to a tick-mark in the upper-left corner).
+Are we sufficiently confused yet?&lt;/para&gt;
+&lt;/glossdef&gt;

+
+<para>That takes care of the glossary database, now you have to get the entries
+into your document. Unlike bibliography entries, which can be empty, creating
+<quote>placeholder</quote> glossary entries would be very tedious. So instead,
+support for <parameter>glossary.collection</parameter> relies on implicit linking.</para>
+
+<para>In your source document, simply use <tag>firstterm</tag> and
+<tag>glossterm</tag> to identify the terms you wish to have included
+in the glossary. The stylesheets assume that you will either set the
+<tag class="attribute">baseform</tag> attribute correctly, or that the
+content of the element exactly matches a term in your glossary.</para>
+
+<para>If you're using a <parameter>glossary.collection</parameter>, don't
+make explicit links on the terms in your document.</para>
+
+<para>So, in your document, you might write things like this:</para>
+
+<informalexample>
+<programlisting>&lt;para&gt;This is dummy text, without any real meaning.
+The point is simply to reference glossary terms like &lt;glossterm&gt;0&lt;/glossterm&gt;
+and the &lt;firstterm baseform="1TBS"&gt;One True Brace Style (1TBS)&lt;/firstterm&gt;.
+The &lt;glossterm&gt;1TBS&lt;/glossterm&gt;, as you can probably imagine, is a nearly
+religious issue.&lt;/para&gt;</programlisting>
+</informalexample>
+
+<para>If you set the <parameter>firstterm.only.link</parameter> parameter,
+only the terms marked with <tag>firstterm</tag> will be links.
+Otherwise, all the terms will be linked.</para>
+
+</refsection>
+
+<refsection><info><title>Marking Up the Glossary</title></info>
+
+<para>The glossary itself has to be identified for the stylesheets. For lack
+of a better choice, the <tag class="attribute">role</tag> is used.
+To identify the glossary as the target for automatic processing, set
+the role to <quote><literal>auto</literal></quote>. The title of this
+glossary (and any other information from the <tag>glossaryinfo</tag>
+that's rendered by your stylesheet) will be displayed, but the entries will
+come from the database.
+</para>
+
+<para>Unfortunately, the glossary can't be empty, so you must put in
+at least one <tag>glossentry</tag>. The content of this entry
+is irrelevant, it will not be rendered:</para>
+
+<informalexample>
+<programlisting>&lt;glossary role="auto"&gt;
+&lt;glossentry&gt;
+&lt;glossterm&gt;Irrelevant&lt;/glossterm&gt;
+&lt;glossdef&gt;
+&lt;para&gt;If you can see this, the document was processed incorrectly. Use
+the &lt;parameter&gt;glossary.collection&lt;/parameter&gt; parameter.&lt;/para&gt;
+&lt;/glossdef&gt;
+&lt;/glossentry&gt;
+&lt;/glossary&gt;</programlisting>
+</informalexample>
+
+<para>What about glossary divisions? If your glossary database has glossary
+divisions <emphasis>and</emphasis> your automatic glossary contains at least
+one <tag>glossdiv</tag>, the automic glossary will have divisions.
+If the <tag>glossdiv</tag> is missing from either location, no divisions
+will be rendered.</para>
+
+<para>Glossary entries (and divisions, if appropriate) in the glossary will
+occur in precisely the order they occur in your database.</para>
+
+</refsection>
+
+<refsection><info><title>Formatting the Document</title></info>
+
+<para>Finally, when you are ready to format your document, simply set the
+<parameter>glossary.collection</parameter> parameter (in either a
+customization layer or directly through your processor's interface) to
+point to your global glossary.</para>

+you'll get the cryptic error: <computeroutput>Warning:

+<para>Make sure there is at least one <tag>glossterm</tag> reference to

+<para>Note that <tag class="attribute">role</tag> is often

+
+<para>If you are using <tag class="attribute">role</tag> for

+value of this parameter. If you forgot you will get document with
+small pieces missing which are very hard to track.</para>
+
+<para>For this reason it is not recommended to use <tag class="attribute">role</tag> attribute for profiling. You should
