I'll second that. By my count, Xerces-J currently has one bug in 
basic XML parsing. (It doesn't report default attribute values from 
the internal DTD subset in invalid documents.) Its nearest 
competitor, the latest Oracle beta, has about ten such bugs. All 
other parsers I've tested are worse.

FYI, you can cut out large chunks of Xerces when building it if you 
don't need them to make leaner and meaner parser. Some of its pieces 
like the WML DOM are really quite unnecessary for most uses.
