[Openid-specs-ab] Reserved member definitions

Just for the record:

WG decision till now is that one is allowed to use different schema than
openid, such as poco.
This is embodied in Message: 3.3.1 schema.

If you want to use short names, you cannot mix from multiple schema.
All the short names are interpreted as the short names defined in the
request schema.
Others need to be defined in URL. (<-- this should probably be URI

The decision has not changed since iiw November 2010.

Since the paragraph is apparently causing some confusions even amongst the
people who were at the IIW November 2010, the paragraph needs to be

Note: Subsequently, we have decided to change member names from camel case
(à la Poco) to underscore separated style (à la FB), but this has not
affected the schema options above, and thus it has been preserved to date.

Now, what each member expresses apart from those defined in the Messages
spec is explicitly out of scope of this specification. An external
specification may define a member called
"http://portablecontacts.net/ns/1.0" <http://portablecontacts.net/ns/1.0> that
has a JSON as a value, but this is out of scope of this specification. It
should be dealt with as an extension.

Our focus right now is to get the main specifications out of door.
Thus, as a co-chair, I suggest to table the discussion until we are done
with the implementors draft of the main specs.
