+++ This bug was initially created as a clone of Bug #7510 +++

I cloned the bug since this is a slightly different issue from what Shelley
raised.

(In reply to comment #15 of bug 7510)
> "The SVG specification states that elements that are not in the SVG namespace,

This seems strange to me.  Defining whether elements are conforming or not is
just a shorthand way of defining conformance of the document in which those
elements reside, right?  So we're really leaving the conformance of

  <!DOCTYPE html>
  <title></title>
  <svg><yowsers/></svg>

undefined?  What should an HTML5 validator report?  Is the conformance of the
document dependent on whether the validator you are targetting supports SVG?

I do think that HTML5 needs to define whether any document is conforming or
not.


Also, the text you added earlier:

  This is because the SVG specification does not define any elements
  called "cdr:license" in the SVG namespace.

is not quite correct.  Well, according to the change referenced in comment #15,
it is neither conforming nor non-conforming.  But assuming that the conformance
of the HTML document fragment is somehow dependent on the conformance of the
SVG fragment as defined by SVG, then it is non-conforming because SVG does not
define an element named cdrU00003Alicense in the SVG namespace.
