Your implication, if I read you rightly, is that it's better to use declarative means to ensure this conformance rather than writing a lot of"code".

My point is that there is more than one way to declare constraints, and I don't think the way enshrined by XSDL is especially useful, nor do I believe it should receive consideration at the expense of other schemes.
