Perhaps.  But XML says that the order of elements is important, so you
can't do that.  It might have been less confusing to you had the various
things you've read said "ordered set," but XML never claimed to be a
mathematical system.

The order of elements matters; the order of attributes doesn't.  It's not
going to change.
