Right, but if you view attributes at "attributes of a type", and
content as "attributes of a type" (syntactic sugar), we get into
a funky world where one asks why you can't specify the ordering
of attributes as you can content. This is kind of where the
SML folk were coming from.
FWIW. I think it would be perfectly reasonable to have a schema
language that had provision for attribute ordering validation,
but I agree that this will almost always be *way* overkill.
I'm actually amazed that SGML is as *usable* as it
is (really!)... when you think of all the alternatives
to unordered attributes, none is anywhere nearly as appealing.
