I completely agree that a grammar is not the place to enforce all the 
special cases of the specification, there are constraints that can't 
be expressed in the grammar, but in this specific case, I can't imagine a 
selector being a HASH and not a HASHIDENT (as specified by '#' IDENT )

If HASHIDENT is not needed, then IDENT is not needed, and we should move 
all the IDENT to NAME and put the constraint in the text of the spec :)
