RE: [xml-dev] Attribute Order

Speaking of XML that is not:

Today I've been staring at an industry spec whose XML data model is not
definable by any schema language that I know of. Validation is currently
done by what I call "little gray boxes": open-source executables that
validate the XML document in nice, lengthy, idiosyncratic C++.

Not being long in XML tooth, I wonder if any of you older hounds might care
to comment on how commonly such is case in the big, wide, metalanguage
world.
