[OpenID] Can't we make openid.ns.sreg attribute a must in OpenID sreg responses?

[Prabath Siriwardena]

As per the spec;
http://openid.net/specs/openid-simple-registration-extension-1_1-01.html
"openid.ns.sreg" is not an attribute that MUST be included in the response.

The spec says; "An Identity Provider MAY return any subset of the
following fields in response to the query."

For example; if you get an OpenID from signon.com; and initiate an
OpenID sreg request; you won't see "openid.ns.sreg" being included in
the response.

But, this makes the life much harder; where we need to differenciate
sreg responses from ax responses.

Can't we make openid.ns.sreg attribute a must in OpenID sreg responses?

Any thoughts?

Thanks & regards.
