It's absolutely native.  The flexibility of the RDF syntax means that
there are plenty of subsets of it which make eminent sense and are good
readable XML.  Here's a bit from one of the hundred-odd RDF sets which
Reuters Health has been publishing daily for more than two years:

Most languages are dramatically underdescribed, and at least one is 
dramatically overdescribed.  Still other languages are simultaneously 
overdescribed and underdescribed.  Welsh pertains to the third category.
