[SVGMobile12] Missing namespace puts document in error

According to section C.4:

# The outermost <svg> element must be defined in the SVG namespace (e.g., 
# <svg xmlns="http://www.w3.org/2000/svg">); otherwise the document is in 
# error.

This seems like a bogus requirement. If the outermost <svg> element 
_isn't_ in the SVG namespace, then it isn't an <svg> element, and is out 
of the scope of this specification, surely.
