It looks like the factories are the bridge between the interfaces and 
the impls, the impls need some schema fluff passed in during

I still have a few concerns.  First you mentioned the usage of xpath, 
when constructing an object with out xml will code that expects xpath 
stuff still function?  Same goes for code what expects the raw xml to 
still be accessible?

Second, it looks like XMLBeans requires XML libs to function, even if 
XML is not used.  Consider an embedded server which does not use XML at 
all... looks like we must still provide XML libraries.  Granted this is 
an off case, but still I would like our binding framework to provide a 
nice clean separation between the POJOs and XML.

BTW, I am not trying to dis XMLBeans, but just trying to understand 
which of the current binding frameworks is best suited for global use 
across the project.
