13. Discovering OpenID Relying Parties

Relying Party discovery allows for software agents to discover sites that support OpenID. It also allows OpenID providers to automatically verify that a return_to URL in an OpenID request is an OpenID relying party endpoint for the specified realm.

Relying Parties SHOULD use the Yadis protocol to publish their valid return_to URLs. The relying party MAY publish this information at any URL, and SHOULD publish it under the realm so that providers can verify return_to URLs.
