[Openid-specs-ab] newbie must be confused at assertion

[hideki nara]

Hi all,

In draft 04 of Message(
http://openid.net/specs/openid-connect-messages-1_0.html),

"1. Terminology" generically says:

Assertion
    A set of Claims about the End-User that are attested to by the
OpenID Provider and Resource Servers.

"3.2.1.  Access Token Request" describes as a parameter such as a
"refresh token":

     The client obtains an access token by authenticating with the
authorization server and presenting its access grant (in the form of
an authorization code, resource owner credentials, an assertion, or a
refresh token).

"3.2.2.  Access Token Response" describes as a concrete entity as
"Positive Assertion" which includes "Access Token" :

    After receiving and verifying a valid and authorized Access Token
Request from the client, the Authorization Server returns a Positive
Assertion that includes an Access Token and an ID Token.

I think newbies will confuse.  Actually I can't tell my friend exactly
what Assertion in Connect means and how differ from OpenID 2.0
Assertion.

Or simply I must  fail to catch the meaning of English word
"assertion" properly...
