Summary: predefined entities...

Initial Comment:
Co-workers and myself have found it useful to be able 
to disable the expansion of default entities under 
certain circumstances.  For example, in a pipeline 
such as:
   app1 | app2 | app3

you only want app3 to actually expand default 
entities, otherwise you'll get wellformedness (is that 
a word ?:) errors if you have a character handler 
installed.

A buddy of mine actually hacked the xmltok_impl code 
and recompiled (which works quite well), but I decided 
to take a stab at providing a function/runtime means 
of changing this behavior.

The attached patch compiles, runs, and it produces the 
expected results against my test cases.

changes include:
   * new func decl in expat.h (or expat.h.in I suppose)
   * a few mods to xmlparse.c

Assigned to me since I'm interested in something similar.

Would you consider is acceptable to get a callback for all references to internal entities?  I'd like to have an event for internal entities defined in the internal subset and predefined entities like "lt" & friends.  You should be able to use a handler for that to present the output you require as well.  This would be useful when building a DOM or generating a SAX event stream that contains all the little niggly details.
