RE: then when a resolver calls the associated VDR using that DID URL, the VDR returns the identified digital resource, not the DID document.

Charles, I'm surprised someone hasn't jumped in n this sooner: what type of resolver are you referring to? ...by that I mean if the resolver is a DID Resolution specification compliant resolver, the resolver can only return DID Document compliant resources (or portions of a DID Document compliant resource). ... if the above is true, supporting a TOIP query string parameter that can return arbitrary JSON structures will break interoperability of the DID ecosystem.

Your thoughts? ...my knowledge of the DID Resolution spec may be out of date.

There is a "resource" DID URL parameter specified by ToIP - could that work?

  https://www.w3.org/TR/did-spec-registries/#resource
  https://wiki.trustoverip.org/display/HOME/DID+URL+Resource+Parameter+Specification
