[OpenID] Signing method for XRD

Let me put this in perspective before before we start going in all
directions.

The whole purpose of XRD was to simplify XRDS. By adding XML-Dsig you are
going back to square A. We might as well stick to XRDS then.

The idea of XRD was KISS - "Keep it simple stupid".

Can you give me one example where "XML Dsig signed SOAP and SAML" is being
used by millions of users in a network?

I am not knocking it down. A whole lot of people seem to be unhappy with
XML-Dsig. You read about it every where you read about XMLDSig. Try
wikipedia for starters.

JSON is a great idea as long as you sign it as is, and apply the
Content-Type, so that it is not modified in transit.
