That's the problem. You can't have it both ways. A polyglot only works 
if the documents include DOCTYPE and XML namespace declarations. 
Anything less than that is all about kicking the can down the road for 
others to pick up. Trouble is that the developer profile associated  
"others" is too pragmatic to bother (and justifiably so) with the 
required content sniffing -- especially when we have Microdata, 
Microformats, and RDFa in the mix.

Let HTML be HTML and XHTML be XML. The retrofitted subClassOf relation 
that now has HTML subsuming XML isn't worth the costs.
