I'll attach the original indexterm.xml DocBook XML; the
XSL-FO produced from docbook-xsl-1.68.1; and the input
to xmlroff, which is the XSL-FO passed through
libfo-compat.xsl.

XSL-FO from docbook-xsl-1.68.1

The libfo-compat.xsl now in CVS correctly handles empty
fo:wrapper.

More work needs to be done before empty fo:wrapper are
usable as targets of cross-references.

Tony.
