ISSUE: Populating SAML Response/Status/StatusCode/Value

PROPOSAL: The following are the only permitted values, as
specified by SAML, with their SAML-specified semantics.  I
propose that the specified XACML status codes be mapped to the
corresponding SAML status codes.

  o urn:oasis:names:tc:SAML:2.0:status:Success
        SAML: The request succeeded.

        XACML: urn:oasis:names:tc:xacml:1.0:status:ok

  o urn:oasis:names:tc:SAML:2.0:status:Requester
        SAML: The request could not be performed due to an error
        on the part of the requester.

        XACML: urn:oasis:names:tc:xacml:1.0:status:missing-attribute

Or should we map this to status:ok at the SAML protocol level?

        XACML: urn:oasis:names:tc:xacml:1.0:status:syntax-error
                 where syntax-error is in Request Context.

  o urn:oasis:names:tc:SAML:2.0:status:Responder
        SAML: The request could not be performed due to an error
        on the part of the SAML responder or SAML authority.

        XACML: urn:oasis:names:tc:xacml:1.0:status:syntax-error
                 where syntax-error is in a Policy or PolicySet.

Remember that syntax-errors in Policy or PolicySet elements are
not always detected in conjunction with a Query, so not all cases
of Policy or PolicySet syntax errors would get reported to a
requester in this way.

               urn:oasis:names:tc:xacml:1.0:status:processing-error

  o urn:oasis:names:tc:SAML:2.0:status:VersionMismatch
        SAML: The SAML responder could not process the request
        because the version of the request message was incorrect.

        XACML: Same as SAML.
