Ah, interesting...that spelling hadn't occurred to me :>
And in fact there already _is_ a binding to it in XML::LibXML!!

But it does do _quite_ a bit more than I had really wanted!
It drops the XML declaration & doctype, converts empty elements
and canonicallizes all space (& newlines). 
Still, it's probably better than dealing with the declarations.

Thanks a lot for the pointer.
