Well-formedness is a prerequisite for validity, but it is not the 
same thing. A document can be invalid but still well-formed.

No. I don't. If it's not well-formed it isn't an XML document,

is not a comment. All well-formedness rules must be adhere to without 
exception. Short of that you don't have an XML document.
