Perhaps. The cans of worms are different though. HTML elements are  
basically content - in principle, the text tree is reasonably useful  
(unless you have images). SVG is about images - having parts of an image  
not render can drastically alter the semantics ofthe image.

SVG has a mechanism for handling broken subtrees, which involves showing  
that it is broken.

Somewhere there might be a sweet spot that we can find with the SVG group.  
But it's not ust a case of "they should do as we do". (And I agree that  
the luxury of having the choice of a strict syntax is nice, and would hate  
to see that baby tossed out with any bathwater we may find in the  
requirement to be intolerant).

cheers
