I'd argue that any spec that imposes additional constraints on 
processors not imposed by XML 1.0 is not compliant with XML. 
Requiring attribute order to be maintained would be one such 
constraint. Another would be treating a character inserted via a 
character reference differently than a character typed literally. 
(WML has this problem.) The documents in such applications might be 
well-formed XML documents, but the processors that handle these 
documents are not compliant XML parsers.
