Really? Not surprising at all? I've never encountered a piece of software where
the order of attributes on an input XML document mattered. AFAICT, you can't
enforce the order of attribute names through a DTD or schema. Even W3C says
"Notethat the order of attribute specifications in a start-tag or
empty-elementtag is not significant." So, to me, it's quite surprising to
encounter a situation where the order of attributes makes such a dramatic (but
non-obvious) difference.

Yep, that's pretty much what I figured. Or just use the includes attribute
instead of file. That seems to work the way you'd expect it to, and the
documentation is clear and unambiguous. I was just hoping maybe someone had
some deeper information on this beyond an interpretation of the documents.
