Re: [OAUTH-WG] draft-ietf-oauth-v2-bearer-09: Open Issues & Proposed Resolutions

The scopes cross all of the profiles.

I expect that restricting the character sets for bearer tokens, MAC, and other future variants should be dealt with in those profiles. 

Without restricting scope in core, we leave the possibility of coming up with different rules in different profiles e.g. MAC vs Bearer.

It is probably best to have one rule in core that works across all the profiles.

They need to live in all the same places (query parameters, headers, forms) that scopes do and would be subject to the same kinds of encoding woes that scopes will. Or am I missing something obvious as to why this isn't a problem for tokens (both bearer tokens and the public part of MAC tokens) but is a problem for scope strings?
