[Openid-specs-native-apps] Please review specs

*Comments on Agent Core 1.0*

5.0 - Do we need to make client credentials mandatory?   Can we make this a
MAY?

7.1 - in general seems redundant to oauth/openid connect, with the
exception of the AZA scope.  Do we need to respecify all of this?

7.1.1 - Why is response_type=code MUST?  Is this oauth carry over?  (same
as my question on 5.0 I think)

7.4.1/2 - By issuing on the token endpoint, we are basically saying that
only administrative authorization models will work.  If end-user authorized
oauth is being used, the user doesn't have a chance to approve access to
and new app.    Shouldn't we be performing a new Authorization request,
rather than a straight refresh token exchange?


*Comments on Agent API bindings 1.0*

2.0 - "Rather than the user individually authenticating and authorizing
each native application, they do so only for the authorization agent"  -
same as my last comment; from an authorization model perspective, this
basically kills off end-user approval models with this profile.   There's
no way for the user to make effective authorization decisions for future
unknown applications.

4.0 - this seems to really be the meat of what we should specify, but the
entire section is basically silent on detail.   For this spec to be
successful, shouldn't we take a stand and actually specify interaction
patterns?

4.1 - "The TA MUST NOT deliver a secondary access token to an application
for which it was not issued." seems at odds with the rest of this section.
  For example, the custom scheme approach would potentially violate this on
iOS.  I'm not certain there is a reliable way not to violate this when
supporting an TA intiated flow.

4.2 - We should really spec out a Native App intiated flow.  It may be the
only way we can reliably handle the security contraint in section 4.1.
 One option could be to issue a public key with the authorization request
and then encrypt the use JWE to responds, so if the Native app's custom
scheme url were hijacked, the returned token wouldn't bleed to the wrong
app.
