New issue 998: subject_types_supported - should or must?

Vladimir Dzhuvinov:

Today an OIDC developer (https://twitter.com/leleuj) informed me about a discrepancy in the OIDC spec regarding the **subject_types_supported** OP metadata parameter:

Core says  


> The OpenID Provider's Discovery document SHOULD list its supported Subject Identifier types in the subject_types_supported element.

Discovery however says that this parameters is required:


> subject_types_supported
    REQUIRED. JSON array containing a list of the Subject Identifier types that this OP supports. Valid types include pairwise and public.
