Depends on the language you are calling Expat from.
In C++ or Delphi I would raise/throw an exception.

In C, one can use setjmp/longjmp. Check out the mailing list
archives - this has been discussed in the past couple of months.

Currently there is no such return value for handlers.
A workaround would be to clear all handlers when the error
is detected, set a flag, and stop processing when the
next call to XML_GetBuffer/XMLParseBuffer comes up.
