Speaking of writing a promising XML parser and then abandoning it, 
what's up with Saxon's AElfred? :-) So far in my tests, it's the only 
one to cross the 90% correct threshold, and many of the tests it 
fails are bugs in the test framework I need to fix.

The major problems in this fork of Saxon appear to be failure to 
detect malformed entities when their resolution is well-formed, 
failure to detect some illegal characters (perhaps it's using Java 
rules rather than XML rules), and failure to absolutize NOTATION 
system IDs.  There are also some namespace issues that probably 
relate to the legal and illegal character testing. If these problems 
were fixed, this branch of AElfred would come very close to 100% 
conformance on the XML 1.0 tests.
