25 <para>The value of | |
26 <parameter>refentry.source.fallback.profile</parameter> is a string | |
27 representing an XPath expression. It is evaluated at run-time and used | |
28 only if no "source" data can be found by other means (that is, either | |
29 using the <tag>refentry</tag> metadata-gathering logic "hard coded" in | |
30 the stylesheets, or the value of the | |
31 <parameter>refentry.source.name.profile</parameter> and | |
32 <parameter>refentry.version.profile</parameter> parameters, if those | |
33 are enabled).</para> | |

36 <para>Depending on which XSLT engine you run, either the EXSLT | |
37 <function>dyn:evaluate</function> extension function (for xsltproc or | |
38 Xalan) or <function>saxon:evaluate</function> extension function (for | |
39 Saxon) are used to dynamically evaluate the value of | |
40 <parameter>refentry.source.fallback.profile</parameter> at | |
41 run-time. If you don't use xsltproc, Saxon, Xalan -- or some other | |
42 XSLT engine that supports <function>dyn:evaluate</function> -- you | |
43 must manually disable fallback processing by setting an empty value | |
44 for the <parameter>refentry.source.fallback.profile</parameter> | |
45 parameter.</para> | |
