RE: XACML TC Charter Revision - Strawman

["Damodaran, Suresh" <Suresh_Damodaran@stercomm.com>]

Here is the revised TC Charter - from the lack of email on this thread
in the past few days, I am assuming that all the comments are already in.

Notes: 
1. Changes from previous version: 
	a) "subject" has been replaced by "target"
	b) "CORBA CSIv2" replaced by "LDAP"
2. Charter is silent on the mechanisms for executing the policy (PDP and
PEP). 
3. Non-goals  of XACML are missing (if any of you want to take a stab at it,
please do)

 Please send your comments.

Product of TC
XACML TC will define a core XML schema for representing
entitlement policies, also called XACML

Policy Target
The target of a policy (hereafter referred to as "target") can be any object
that can be referenced in XML.

Protocols and bindings
XACML TC will define new protocols or identify bindings
to existing protocols (e.g., XPath, LDAP) intended as means of accessing and
communicating the policies

Scope
XACML is expected to address fine grained control of
authorized activities, the effect of characteristics of
the access requestor, the authorization protocol over
which the request is made, authorization based on classes
of activities, and content introspection (i.e. authorization
based on both the requestor and potentially attribute
values within the target where the values of
the attributes may not be known to the policy writer)

Extensibility
XACML core schema is extensible for as yet unknown features

Interoperability

XACML TC will define interoperability of XACML core schema
with other standards.
