It's not really necessary for 3.3.x, since the XML parsing requirements for
Tomcat are pretty limited (without looking, we are currently shipping with a
jaxp1.x version I believe).

I'm +0 as long as the lib/endorsed directory is empty in the default
install.  Otherwise, I'm -1.

The Tomcat 3.3 ClassLoaders are all delegating loaders (so it is much
simpler than the 4.x/5.x case).  If you are using a 1.4.x JVM, Tomcat 3.3
will always grap the XML parser from the System ClassLoader (either the one
that ships-with, or the endorsed).
