Well, the problem is that they would mean different things. Consider the  
following fragment:


In a tree, that would look like:


And not, as you might expect:


This problem is actually as simple as:

   <!doctype html><foo/>

I suppose there is some subset of HTML5 documents that would mean the same  
when processed with an XML processor... I don't really see any value in  
imposing restrictions on all HTML5 documents to conform to such a subset  
though. Especially as you have to support a much wider variety of  
documents anyway.
