The answer was actually IE (depending on what you mean by contains, it's 
only used if you load documents by scripting and specifically ask for 
validation).

Mozilla does not have a validating XML parser see

https://bugzilla.mozilla.org/show_bug.cgi?id=196355 

and specifically about XHTML:
"Despite common allegations to the contrary, the document is not checked for 
validity. "
