This seems like a pretty bold statement to make, and it contradicts my 
experience. There are companies that started using XML fairly early and 
many of the applications that were developed were not upwardly 
compatible.  The problems we are have had is not with attributes but with 
encrypting element content.  Inserting new elements into what is expected 
to be only CDATA is the main problem that I have seen (especially for DOM 
parsers). We cannot tell a paying customer to redesign their legacy 
applications and XML vocabularies.
