"Handling" I suppose is a vague term, but XML and text/plain describe 
neither rendering, semantics, nor behavior. They say absolutely nothing 
about what a processor should or must do with any given byte stream or 
what meaning it infers to those bytes. They describe syntax, nothing more.

CSS and PNG describe rendering--that's their whole purpose--but not 

HTML 5 attempts to prescribe almost everything. It is far more demanding 
and less flexible than previous specs.
