assign category membership semantics to an entity, and a second
attribute for use in claiming interoperation or support for entities
in such categories.

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,
to influence user interface decisions such as those related to
identity provider discovery, or for any other purpose. In general,
the intended uses of any claim of membership in a given category will
depend on the details of the category's definition, and will often be
included as part of that definition.
Entity category attribute values are URIs, and this document does not
specify a controlled vocabulary. Category URIs may therefore be
defined by any appropriate authority without any requirement for
