The former is Sun's fork of Xalan, which ships with the JRE, just like
their fork of Xerces. From numerous posts on XML-related lists and from
my own experience I know that it's best to avoid them because they have
numerous astonishing bugs, especially with JDK 1.6.

Yes. always use the original Apache versions.

I've never used that, so I can't comment on this one.

Alright, Java 6, so get rid of the Sun forks as soon as possible.
Simply drop the Apache versions into your extension directory.

As far as I know, not even off of some stable release. If you want to
know, ask Sun.
