How about:

DESCRIBE is currently not constrained at all. The Working Group felt 
that the abstract functionality was useful, but there was little field 
experience to guide standardization. The most common understanding of 
DESCRIBE is that it returns an subset of the queried graph that is 
relevant to the resource, but the nature of the relevance function has 
not been settled. Furthermore, it's possible that other relations 
(e.g., metadata not in the graph, statistics about the resource, etc.) 
and other return formats (HTML) may be part of the DESCRIBE form.

Hmm. This is all non-normative, except maybe the first sentence. 
Frankly, I think that is as it should be. Since it really *isn't* 
specified, even to the small degree hinted, we shouldn't pretend it is.
