It is funny (perverse?) to  see someone trying to define a structure
language without the help of a structure language, when one is
available :-)  But I guess it is a sign of draftiness rather than
daftness.  

Here is an stab at the MCF schema description language using WebSGML.
":" must be NMCHAR character.

Try doing this without parameter entities
