New Revision: 327084

URL: http://svn.apache.org/viewcvs?rev=327084&view=rev
Log:
Proving of concept. Cloning of an OMElement can be easily achieved by the concept tested in this test case. 
If we want to clone elementOne, get a pull parser (of course SHOULD be with caching) from elementOne. Create a StaxOMBuilder from that and get the document element. That is a clone of elementOne.
