Summary: Way for handler to report parse errror

Initial Comment:
There also appears to be no way for a content handler 
to return an failure case back to expat.  Just because 
the xml is well formatted, does not mean that the data 
inside is.  All of the handler calls just return void, and 
call the next routine.  If exceptions are expected to be 
used, then make sure that path is exception safe.

Expat concerns itself with well-formedness only.

However, if you wish to abort parsing for any reason,
there are several ways to terminate:

- use exceptions (this works for me)
- use setjmp/longjmp
- use the new feature XML_StopParser() which you have
  to call from a handler.

The third feature is currently available as patch #835123
only, but should make it into one of the next releases in
some form or another.
