Sure, we have to do something about it.  I'm just not sure what that is, 
yet, and haven't seen a solution that I think it satisfying.  I don't 
think that Henri's proposal would yield results that authors would 
expect (if they made a mistake).  My proposal of magically sniffing out 
that it's SVG and treating it as such has a whole different set of 
problems.  I'd be interested in hearing something more compelling.

I don't see how there could be, of course.  But the solution that's 
decided upon may be affected by which case we're trying to address.  If 
we are trying to correct a mistake in how the file is presented, we may 
wish it to be treated as normal SVG, with SVG's parsing rules, while if 
we are trying to allow SVG-parsed-as-HTML as a use case, we would treat 
it elseways.  Obviously, I don't tend to favor the latter.

In either case, I don't think non-XML SVG should ever be conforming (as 
XML stands now)... it should simply have reported error correction 
applied to it in the text/html case.
