[XML-SIG] Noisier error handling all 'round?

[Paul Prescod]

It doesn't matter much one way or the other because the SAX interface
should be more often used. The speed freaks who code directly to Expat
(it may not buy much at all, actually...) can read the documentation or
sample code or whatever.

But that begs the question of what saxlib does and it does NOT, by
default raise an exception. It should. For all parsers the driver should
set it up so that the "default error handler" raises an exception.
