<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>
