ISTR this is a libxml2 thing - the entities are correctly encoded and
parsed by libxml2, but when they are output there is no requirement on
libxml2 to turn them back into entities - it is just as legal (and
results in a smaller document) if they are left as (I assume) UTF-8
characters.

Nick, does mod_proxy_html set/alter xmlSubstituteEntitiesDefaultValue
(from <libxml/globals.h> ? I think this controls the behaviour on
parsing a document.

Cheers
