                     draft-young-entity-category-05

Abstract

   attribute for use in claiming interoperation with or support for
   entities in such categories.

   This document is a product of the Research and Education Federations
   (REFEDS) Working Group process.

1.  Introduction

   This document describes a SAML attribute, referred to here as the
   "entity category attribute", values of which represent entity types
   or categories.  When used with the SAML V2.0 Metadata Extension for
   Entity Attributes [SAML2MetadataAttr] each such entity category
   attribute value represents a claim that the entity thus labelled
   meets the requirements of, and is asserted to be a member of, the
   indicated category.

   These category membership claims MAY be used by a relying party to
   provision policy for release of attributes from an identity provider,
