Problem with resolution of entities

[Ron Catterall <ron@catterall.net>]

Docbook 5, xsl 1.75.2, Oxygen 11.0 MacOS 10.4.11 Saxon 6.5.5 XEP 4.16 -
FO to PDF
I find that set theory symbols (∩ etc) resolve correctly in
footnotes to text in a <para> and in footnotes to text in a
<table><info><title>, but do not resolve in text (<para>) or text in
<table><tgroup>(<thead>|<tbody>)<row><entry>.  I have tried both entity
names (&cap; etc) and code points (&#x2229; etc) - both react the same way.
Looks like a bug, but any suggestions/help welcome.
