There is no model for when validity errors are guaranteed to be fired.
A parser is free to fire them when it detects them, or even to save them
up to the end of the document and fire them all at once.  (Indeed, validity
errors like undefined ID *can't* be detected until the end.)

I suggest switching from a SAX to a DOM model.  You can use my DOMParser
( to walk the DOM tree after it's generated.
