Simple enough spec. I like the notion of service type. However some questions to answer:

How would one convey saml2:Assertion as the "principal"? Or how would one convey a saml2:NameID as the "principal"?

Or in more generic sense, how would one convey a pairwise pseudonym as principal?

> Having a simple discovery method for services and resources is key to enabling many Internet scenarios that require interactions among parties that do not have pre-established relationships.  For instance, if Joe, with e-mail address, wants to share his calendar with Mary, then Mary's calendar service, in the general case, will need to discover the location of Joe's calendar service.  For example, Mary's calendar service might discover that Joe's calendar service is located at by doing discovery for a service named  at for the account joe.

SWD is simple to understand and implement, enables different permissions to be applied to discovery of different services, and is JSON-based.  I look forward to discussing this with many of you next week at IIW<>w/>.
