This is too subtle for me. Do you mean that you actually want to write
stuff like <http://purl.org/dc/elements/1.1/source> inside the XML
representation of N-triples?

I meant that there is a reasonably simple XML language that is isomorphic
to N-triples. This is all you need. Write in a simple non-XML surface
language and have machine translate it into XML. XML is not for people --
it is for machines. All you need is a 1-1 mapping between a
human-friendly surface language and machine's.
