[WG-UMA] New version of draft

here some thoughts about extending client registration for special case...

A special case of Client Registration is when the Host (in UMA terminology) is an Identity Provider/Claim Issuer (as discussed in the Trusted Claim approach).

For trust management reason, the Authorization Server, in order to verify the client's Identity Assurance Level, may checks IdP (whitelist) from a Trust Framework provider (also discussed in the doc Trusted Claim approach - Identity assurance feature sub-paragraph - sent out by Eve).

To comply this specific scenario, the (push) client registration request may also includes the following parameters:

- IdP domain name (e.g. idp.booble.com)
- Level of Assurance (e.g. LOA_Reference=2)
- Trust Framework provider reference (e.g. https://secure.globaltrust.org/IdP/whitelist)

(attached a diagram/flow about Client-Authorization Server and TFP interactions).

1. Authorization Manager is able to verify if the IdP domain is certified from a TFP with which LOA, before to release client_id and secret.
2. Authorization Manager obtains "certified meta-data" from the TFP about the IdP.

The following links provide an interesting references about trust management aspects:
- http://www.idmanagement.gov/documents/ICAM_OpenID20Profile.pdf   (par. 2.7 Programmed Trust pag. 15)
- http://www.xmlgrrl.com/blog/publications/#oitf

hope it's useful for the discussion.
