Right, I get that; that's why I was wondering about its use in SCXML (as 
opposed to multiple xsd:keys).

I would guess it's mainly for compatibility with DTDs.

OK. My main reason for asking was that for implementations with a 
non-validating XML parser, it's an extra enforcement step for keyspaces
