[rules-dev] Dom element for ExtensibleXmlReader

[Mark Proctor]

Krisv,

I have removed the Configuration interface and implementation and 
implemented everything to use DOM and Element. I've updated all the 
tests and it seems to be working:
http://jira.jboss.com/jira/browse/JBRULES-1634

I have not yet updated the Semantic Modules to allow DOM handler, I'll 
do that tomorrow along with attempting to do a JAXB one. But hopefully 
what I've done already is enough for you to do the OSWorkflow mapping.
