In a little note "Richer Anonymous Content Types" 
 http://www.ascc.net/xml/en/utf-8/anonymous.html
I have suggested that there are other declared content
types apart from EMPTY and ANY that might be
useful for XML Schemas.   (The content typing is anonymous
in that it specify kinds of content models without
actually naming the element types. This might fit in
with XML document usage better than simple
"open" and "closed" content models.)

I suggest:
SINGLE 
PAIR
PAIRS 
SAME 
LEAF 
LEAVES 
UNIQUE
NONRECURSIVE
