Right... and this whole discussion started because of the lack of 
clarity there. My assertion is that we'd be better off taking all 
processing-specific notions out of the grammar, and specifying them 
elsewhere... because ultimately, I can choose to ignore or implement 
behaviour as I wish.

I think that's open to debate... I understand perfectly well where 
you're coming from, it's just that in reality, few people make that 
distinction. In a database that includes XQuery support etc. but which 
also support the notion of "checkin/checkout", people *will* get upset 
if things get munged much. It doesn't matter how many times you tell 
them that this is correct behaviour.
