True.  I suppose that is sufficient of an indication of where other  
problems might originate.

When you consider the broader context, it would.  The first example would  
lead a conformance checker to complain about duplication of the <html>  
element if one was present later on in the document, and the second might  
lead a zealous checker to complain that no document language was  
specified.  Or at least I assume these would happen; I haven't stepped  
into the terrifying domain of the tree builder yet.

Still, I will concede that these are in the realm of edge cases probably  
not worth worrying about; forget I said anything. :)
