Recently, in "Re: Confused about & in entity literal", John Cowan wrote (re
parsing after the "&" character):

I'm trying to parse and index documents that contain several HTML-style
general entities ("©", "•", etc.), using Expat ("Version
19990307") as the parser.  I want to be able to trap these entity strings
(they're not to be indexed, but they are to be included, untranslated, in
the document output).  But, Expat exits with an XML_ERROR_UNDEFINED_ENTITY
error ("..undefined entity at line..").  Inspection of the Expat source
shows the following:
======= Begin code excerpt =======
 entity = (ENTITY *)lookup(&dtd.generalEntities, name, 0);
 poolDiscard(&dtd.pool);
 if (!entity) {
   if (dtd.complete || dtd.standalone)
     return XML_ERROR_UNDEFINED_ENTITY;
   if (defaultHandler)
     reportDefault(parser, enc, s, next);
======= End code excerpt =======
Thus, it would appear that Expat is indeed trying to validate the entity
name.  Is this indeed wrong, as John Cowen said?

I've setup both XML_SetDefaultHandler() and
XML_SetExternalEntityRefHandler(), but neither of these functions are
being called by Expat (little wonder, given the above code excerpt).  Do
y'all know what i might be doing wrong here?
