The language - XML in this case - specifies the syntax rules. The DTD
defines what elements are permitted in the document, and how they should
(or should not) be used to structure the document. Neither enforce any
rules.

If you're serving this as application/xhtml+xml and the user agent is a
'conforming user agent' (in the specification sense), then as I
understand it, the software should flag that as syntax error and stop
parsing. If it's also a validating parser (and it gets far enough into
the document), it should notify you that the markup is invalid.
If those conditions aren't true, the actions taken by a user agent are
implementation dependent.
