Given the current way DOCTYPEs work, as well as the desire voiced by many on 
this list to be able to validate fragments, we'd probably do better to leave 
roots out of it.  It remains an important issue, however, for whatever we use 
to link an XSchema to a document.  Do we need/want to declare a 'Root' element 
there?
It seems to me it could be optional, provided that whatever authors choose as 
their root contains the content model specified for it by the schema.  This is 
an issue we need to address.
