I agree with Michael.

I also go so far as to say that the discussion is a bit misdirected: 
the apparently poor encapsulation of Source is more of a symptom of the 
fact that TrAX transformers (e.g., XSLT processors but potentially STX 
or XQuery or...?) need to be able to implement their underlying model 
however they so choose.  Source is little more than a marker interface, 
and the thing that makes sense (at least to me) is to have 
off-the-beaten-path Source implementations (e.g., for a pull parser) 
exhibit enough polymorphism (implement SAXSource, DOMSource, etc.) to 
make them useful and reasonably portable for consumption by different 
Transformer implementations.
