No, I'm not talking about CDATA blocks. I was pointing out that is
legal under XML to have a series of attributes in the same container
level be ordering indefinite. There are other bits (but I can't
remember off the top of my head), but effectively, certain portions of
XML documents are effectively hashes, where the order is not
significant, only the keys.

But the fact is that even if an XML document consists solely of text, it
is not necessarily a text document. This is why XML editors and XML
diff programs are so complex.
