xmlc 2.2 alpha 4

Sorry that this takes a while. I finally get around to do the name 
space renaming and has uploaded it to

http://homepage.mac.com/taweili/XMLC.html

It pass most of the unit tests (those fails are with layout 
inconsistency due to the name change from org.apache to 
org.enhydra.apache). The demo app is working.

The namespace of the modified Apache Xerces parser has been moved from 
org.apache to org.enhydra.apache. Now, the application deployment 
should not run into conflict with the existing Xerces bundled with the 
run time.

Feedback and suggestion is appreciated.
