Subject: [PR] 15-day Public Review for SAML 2.0 Profile of XACML, Version 2.0

The OASIS eXtensible Access Control Markup Language (XACML) TC [1]
members have produced an updated Committee Specification Draft (CSD)
and submitted this specification for 15-day public review:

SAML 2.0 Profile of XACML, Version 2.0
Committee Specification Draft 04 / Public Review Draft 03
22 September 2011

Specification Overview:
This specification defines a profile for the integration of the OASIS
Security Assertion Markup Language (SAML) Version 2.0 with all
versions of XACML. SAML 2.0 complements XACML functionality in many
ways, so a number of somewhat independent functions are described in
this profile:

1) use of SAML 2.0 Attribute Assertions with XACML, including the use
of SAML Attribute Assertions in a SOAP Header to convey Attributes
that can be consumed by an XACML PDP,
2) use of SAML to carry XACML authorization decisions, authorization
decision queries, and authorization decision responses,
3)use of SAML to carry XACML policies, policy queries, and policy
query responses,
4) use of XACML authorization decisions or policies as Advice in SAML
Assertions, and
5) use of XACML responses in SAML Assertions as authorization tokens.

Particular implementations may provide only a subset of these functions.

TC Description:
The XACML Technical Committee defines a core XML schema for
representing authorization and entitlement policies.

Public Review Period:
The public review starts Friday, 14 October 2011 and ends 29 October
2011. The specification was previously submitted for a 30-day public
review on 7 May 2010 [2]. This 15-day review is limited in scope to
changes made from the previous review.

Changes are highlighted in the diff-marked PDF file included in the
release package.

This is an open invitation to comment. OASIS solicits feedback from
potential users, developers and others, whether OASIS members or not,
for the sake of improving the interoperability and quality of its
technical work.

files are available in the ZIP distribution file at:

Version 2.0, we call your attention to the OASIS IPR Policy [3]

members of the TC should be familiar with this document, which may
create obligations regarding the disclosure and availability of a

an approved OASIS specification. OASIS invites any persons who know of
any such claims to disclose these if they may be essential to the
implementation of the above specification, so that notice of them may
