Is this a given ?  Is it even desirable ?
And what does it really mean ? That a document
written in HTML5 will display  "correctly" in
browsers that are HTML5-unaware ?  That's
demonstrably impossible, unless HTML5 is
a strict /subset/ of earlier incarnations
of HTML (as opposed to superset, which an earlier
correspondent proposed).

I remain unconvinced that defining error handling
for "existing content" is a worthwhile (or even
achievable) exercise.  By all means define error
handling for HTML5; even -- if you must -- allow
a conformant HTML5 user agent to recover gracefully
from /some/ (but clearly not all) syntactic errors;
but please don't waste time defining how to process
tag soup.
