Your problem is not with XOM. This is an XML issue. ANY means that 
you can have any declared element, not any element at all. (Of 
course, you can have any element at all. The document just wouldn't 
be valid.)

That's fine. Do that. It will work. Validity is optional, not 
required. XOM always resolves entity references. It will only 
validate if you tell it to do so. (though now that you mention it, I 
wonder is there should be a way to parse a document while validating 
without throwing an exception. Hmm, I need to think about that.)
