You can get a long way by grepping for '="en"/>'  

as in:
		<ServiceName xml:lang="en"/>

Outside tests, I've not seen:
		<ServiceName xml:lang="en"></ServiceName> 

But '"en"></' might be another pattern.

If you are prepared to build from master (which will be 4.0.1) 

	1) it will not fail and
	2) It will give somewhat better warnings on the bad data which might help
