It does not currently support that. There are no alternative 
implementations I'm aware of. It might be possible to write it either 
directly into XOM, or as a subclass if I knew a little more about it. 
I'm not 100% clear myself on just how exclusive canonicalization 
differs from regular canonicalization. Can you summarize the 
difference?

Off the top of my head, I vaguely recall that the difference only 
mattered when canonicalizing node-sets, not when canonicalizing full 
documents, but I could easily be wrong about that. Currently XOM only 
supports canonicalization of full documents.
