Hi Benson,
As Michael notes, Xerces is now shipped with the serializer.jar
(which contains the xalan serializer). If you have this on your
classpath it will be used.
If you leave it out, then xerces will fall back to it's own
(deprecated) one.
regards

Hi Michael,
So, if I put Xerces and not Xalan into classpath, and ask a
document for it's implementation, and ask that for the
DOMImplementationLS, what do I get? Whatever Sun tossed into the
pot? And if I then add Xalan, do I get the right one?

Hi Benson,
We're talking about two different implementations of the DOM Level
3 LSSerializer, the more recently developed one in Xalan
(serializer.jar which Xerces now ships and shares with Xalan) and
the much older deprecated one in Xerces. If you're curious about
the history on that, there's an FAQ [1] on the website.
Some users have decided to keep using Xerces' deprecated serializer
due to some quirks and issues with the currently available one from
Xalan. Folks really should be opening JIRA issues [2] against
Xalan, so those problems get addressed there. There's no intention
to do any further development or fixes to the one in Xerces.
Thanks.
