If I might channel Mark for a moment (Mark, I'm sure you'll jump in  
if I misinterpret), I think there's an unstated assumption in his  
reasoning that might clarify things. AIUI, Mark believes that there  
will/should only be a few standard formats in use (e.g. Atom for list- 
type data, XHTML for form type data etc) and that such a constrained  
world is more amenable to general-purpose processing modules, one per  
format, each of which fully groks the format it is intended to  
process and the semantics of data and metadata contained therein.

Personally, even if the above turns out to be the dominant paradigm,  
I still think there's utility in setting out a map of the available  
resources and their supported methods and representations and with  
APP and OpenSearch we already have existence proof that such  
descriptions are useful. I just hope we can avoid a plethora of such  
description languages.
