I also feel there is value including the word 'generic' as above.

I apprecaite the WG taking the time to consider these concerns.

The proposed text is certainly a move in the right direction, however,
I would have liked to have seen such a reference to CBDs expressed in
a form that would provide more guidance to implementors who have no
idea what form of description to return. E.g.

    "Possible generic mechanisms for deciding what information to return
    include Concise Bounded Descriptions [CBD] which can offer a  
reasonable
    default form of description in the absence of any special  
requirements."

The above text, or something akin to it, would be far better, as it
provides very important guidance to implementors facing the question
"How do I respond to a DESCRIBE request if I myself have no special
goals/features in mind for such descriptions?" And that is a question
that most, if not all, implementors will eventually have to ask, and
I think the SPARQL rec should provide an answer, even if only through
a somewhat subtle pointing of the elbow...

Regards,

Patrick
