I don't think this meets the legacy content mangement system 
requirement. Specifically consider a text/html blog that chooses to put 
its content (potentially including user-entered content) inside a svg 
foreignObject (to use filters or transforms on the content, for example) 
so the embedding is html -> svg -> html. Your scheme would effectively 
cause draconian error handling of the whole page in this case.

It would also be slightly odd to have a scheme where the UA has to 
recover from the error and parse the entire SVG/MathML fragment (to 
determine the location of the closing tag) but was not allowed to 
display any of the parsed content to the user.
