25 | <para>The value of

26 | <parameter>refentry.manual.fallback.profile</parameter> is a string
|
---|
27 | representing an XPath expression. It is evaluated at run-time and
|
---|
28 | used only if no "manual" data can be found by other means (that is,
|
---|
29 | either using the <tag>refentry</tag> metadata-gathering logic "hard
|
---|
30 | coded" in the stylesheets, or the value of

37 | Xalan) or <function>saxon:evaluate</function> extension function (for

39 | <parameter>refentry.manual.fallback.profile</parameter> at
|
---|
40 | run-time. If you don't use xsltproc, Saxon, Xalan -- or some other

41 | XSLT engine that supports <function>dyn:evaluate</function> -- you
