Heh, about an hour after I posted my original post, I came across the
<interleave> node. Bravo to RelaxNG for allowing flexible node ordering.

I suppose the main reason for wanting/needing unordered (or any-ordered)
elements is if you're receiving XML documents from different sources, be it
applications or users/vendors. It seems to be a serious pain to report back
to them that the document failed validation just because element "B" was
listed before element "A"...
