Yes, I think you're right, that this is not correctly testing XML EC14N. Further more, there is no RDFa 1.1 test for it (I don't really exactly why 0011 was removed, but it wouldn't have generated an XMLLiteral in RDFa 1.1 anyway).

I'm reluctant to add such a test to XML and XHTML1 before REC, but we can fix the 0212 for RDFa 1.0 and add a new one that works with XHTML5 and SVG.

Suggestions?
