1.  Introduction

   Policy applications often apply common policies to multiple
   authorized users.  Bulk operations are often applied through the use
   of group naming, e.g. 3GPP's use of Base Name.

   This document defines a grouping mechanism to apply common operations
   to a group of policies and a membership set that can be used to
   quickly apply one or more Diameter based policies, e.g.  Filter-Rule
   [RFC5777] to authorized users.

2.  Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   document are to be interpreted as described in [RFC2119].

3.  Terminology

   Authorized Users  An Entity that has been authorized to use a service
      via a Diamater Application.

   Base Name  An organizational structure used to define a domain for
      multiple Policy Groups or Membership Domains.

   Determination Type  The matching policy applied, e.g.  ANDMASK, AND,
      etc, for Membership Determination.

   Policy Entity  A type that may be assigned to a Policy Group or
      Membership.  This includes but is not limited to Filters [RFC7155]
      or Filter-Rules [RFC5777].

   Membership Determination  The process by which Policy Entities are
      selected to be applied to an authorized User.

   Membership Domain  A name assigned to a Membership Set.

   Membership Value  A binary set of values where each bit represents a
      specific membership pattern.

4.  Concepts

   Policy Groups represent a union of Policy Entities.  These entities
   MUST be of the same type, e.g.  Filters [RFC7155] or Filter-Rules
