Hi, Guys-

I put an RDF license in an <svg:metadata> element, as is common practice 
for Inkscape-generated content, and tried to validate it.  The validator 
complained, no matter which method I tried, either including the 
necessary namespaces in the RDF root [1], or in the SVG root [2]. 
Either should be legal, and should validate (unless I'm confused).

This is problematic for 2 reasons:

1) the SVG spec explicitly uses examples of this
2) there is a lot of SVG content (mostly generated by Inkscape) on 
Wikipedia, which wants the license info to be clear.

There are other combo options that the validator claims to understand, 
including XHTML + RDFa, XHTML 1.1 plus MathML 2.0, XHTML 1.1 plus MathML 
2.0 plus SVG 1.1.  Is it possible to get RDF put into that list?

More concretely, are there specific problems that make that difficult? 
Is there something I can do to help with the issue?

(Note that Validator.nu doesn't validate RDF at all, so no help there.)
