refentry.source.fallback.profile — Specifies profile of "fallback" for refentry "source" data
<xsl:param name="refentry.source.fallback.profile"> refmeta/refmiscinfo[not(@class = 'date')][1]/node()</xsl:param>
The value of
refentry.source.fallback.profile is a string
representing an XPath expression. It is evaluated at run-time and used
only if no "source" 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 the
refentry.source.name.profile and
refentry.version.profile parameters, if those
are 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.source.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.source.fallback.profile
parameter.
