best XSLT processor?

[uche.ogbuji at gmail.com]

Xalan is certainly faster, but it is almost certainly not more
compliant than 4Suite.  Xalan actually has a bit of a reputation among
XSLT processors in its carelessness with compliance.  But I suppoose in
order to settle these counter-claims, one of us will have to come up
with specific compliance examples.  You fired the first shot.  Can you
back it up?
