GNU JAXP, Piccolo, and the other AElfred derivatives

Perhaps. The current situation is untenable though. Some hard choices 
need to be made, sooner or later. As it stands, SAX is severely 
underspecified, parsers do exhibit varying behavior, and programs are 
not interoperable between parsers (and this is hardly the only area 
where that is true). The failure to produce a test suite in 
conjunction with the specification was a major error, but one I hope 
to begin rectifying soon.
