<!-- This module contains templates that match against FO nodes. It is used
     to post-process result tree fragments for some sorts of cleanup.
     These templates can only ever be fired by a processor that supports
     exslt:node-set(). -->

<!-- insert.fo.fnum mode templates insert a particular RTF at the beginning
     of the first paragraph in the primary RTF. In fact, they are inserting
     a footnote-number, so we tinker a few other things too, like spacing and
     font-sizes. -->
