The problem arises from having to create _another_ structure-handling layer 
(a layer to handle CLASS) over SGML's structure-handling layer.  Whereas if 
SGML handles the structure directly, we can make use of the experience and 
tools derived from SGML usage.

The problem of arbitrary content models should be easier with arbitrary 
GI's, as at least we have SGML for that -- implementing CLASS as the main 
structure expression avenue would require creating yet another structure 
handler for an as-yet undefined language.
