In the past, Mandatory Access Control (MAC) systems have used very
rigid policies that were implemented in particular protocols and
platforms.  As MAC systems become more widely deployed, additional
flexibility in mechanism and policy will be required.  While
traditional trusted systems implemented Multi-Level Security (MLS)
and integrity models, modern systems have expanded to include such
technologies as type enforcement.  Due to the wide range of policies
and mechanisms that need to be accommodated, it is unlikely that the
use of a single security label format and model will be viable.

To allow multiple MAC mechanisms and label formats to co-exist in a
network, this document creates a registry of label format
specifications.  This registry contains label format identifiers and
provides for the association of each such identifier with a
corresponding extensive document outlining the exact syntax and use
of the particular label format.

This document is a product of the Network File System Version 4 Working Group of the IETF.

This is now a Proposed Standard.
