I have  a couple of comments on this draft.  The first is editorial, and 
I'm afraid the second will cause some consternation, but anyway:


Section 4:

"In its finding on how responses to requests for resources which are not 
information resources should be constructed [HTTPRANGE] ,the TAG 
recommended that documents descriptive of non-information resources should 
not be simply returned normally in response to requests for URIs which 
identify those resources. " 

This sentence seems a bit convoluted and difficult to parse.  Lots of 
"not"s and "non-"s.


Section 4:

"Since a namespace document is precisely such a descriptive document, and 
namespaces are not information resources..."

Well, as of the Southampton meeting, we don't have consensus that 
namespaces are not information resources.  I think they are (a collection 
of allocated names, the list of which can typically be conveyed either 
extensionally or intensionally in a message, and is this an information 
resource), and Tim believes that namespaces are not information resources. 
 We do agree, however, that even if a NS is an information resource, it is 
not  the information resource that is the descriptive document with links 
to schemas, etc.  That's a separate resource and it is definitely IMO an 
information resource.  Might we avoid having to settle the question be 
rephrasing as:

"Since the Web resource that is the description of a namespace is clearly 
distinct from the resource that is the namespace itself, the two should in 
general have separate URIs.   What should be done to facilitate finding 
one from the other?"
