refentry.manual.fallback.profile string refentry.manual.fallback.profile Specifies profile of "fallback" for refentry "manual" data refmeta/refmiscinfo[not(@class = 'date')][1]/node() The value of refentry.manual.fallback.profile is a string representing an XPath expression. It is evaluated at run-time and used only if no "manual" data can be found by other means (that is, either using the refentry metadata-gathering logic "hard coded" in the stylesheets, or the value of refentry.manual.profile, if it is enabled). Depending on which XSLT engine you run, either the EXSLT dyn:evaluate extension function (for xsltproc or Xalan) or saxon:evaluate extension function (for Saxon) are used to dynamically evaluate the value of refentry.manual.fallback.profile at run-time. If you don't use xsltproc, Saxon, Xalan -- or some other XSLT engine that supports dyn:evaluate -- you must manually disable fallback processing by setting an empty value for the refentry.manual.fallback.profile parameter.
