On a more fundamental level, "Tag Soup HTML" has infinite ways that it 
can be broken, since there is no guarantee of correctness, and even 
worse, browsers are expected to accept this tag soup that doesn't come 
near validating.

XML based things like SVG have a well-formedness guarantee that make 
them so much simpler to deal with.  If it fails, you simply reject the 
entire thing.

This is why a usable web browser is 25-30 megs and a usable SVG library 
is 200k.
