ID wording

[Paul Hoffman / IMC <phoffman@xxxxxxx>]

Greetings again. Thanks for keeping the moratorium on ID discussion. 
I thought it would be best to do a sanity check to be sure people 
were in agreement on what it seems the consensus so far was.

- The format for IDs is going to be URIs, not plain strings.

- IDs must not change over time.

- Even though the format is a URI, the IDs are not expected to be 
dereferencable (although they might be).

- IDs MUST be compared character-by-character, no case-mapping, no 
%xx conversion, and so on.

- Receiving and gateway systems MUST NOT alter IDs in any way.

- Because IDs might be dereferenced, and because they must not be 
changed, it is a good idea to create them in a canonicalized form. 
There is no interoperability issues with this suggestion, so it is 
just a suggestion, not a SHOULD-level suggestion.

Does this match what people feel was the general consensus?
