Colleagues,

I enclose a first proposal for the division of work among different task
forces within the new Schema subcommittee. The rationale for the two main
task forces would be focusing:

1. on the definition of XML types representing a policy and policy
combinator, leaving rules as black box elements

2 on the definition of XML types representing rules and their internal
structure

Two minor task forces should deal with identifiers and obligations; I aslo
included a task force on extensibility points.

Of course this proposal is only a raw first attempt, made to be amended
and modified by your input via e-mail. I especially encourage Tim feedback
on my subdividing the current schema types among thematic task forces, I
surely made many mistakes. Proposals for modifying this task force list
(or having a completely different one) should be discussed on the list in
the next few days. Once we have a task force list in place (hopefully to
be approved by next Monday), people can start joining the task forces and
working off line at fine tuning the parts of the schema under their
bailiwick.

From that point on, our Moday concall will be mostly dedicated to
reviewing and approving decisions and modifications that the different
task forces will proposed.

What do you think?

XML SCHEMA SUBCOMMITTEE

TASK FORCES ON POLICY SYNTAX 

1. TASK FORCE ON POLICY-LEVEL TYPE SYSTEM

This task force will focus on XML types representing policy combinators, individual policies and their components, 
as well as on elements belonging to those types. Internal structure of policy components will not be defined by this task 

force.

Current schema reference types:

Complex type PolicySetStatementType 
Complex type PolicyStatementType
Complex type PolicySetType 
Complex type PolicySetDesignatorType 
5Complex type PolicyDesignatorType 
Complex type RuleSetType 
Complex type RuleDesignatorType 
Complex type RuleType

2. TASK FORCE ON RULE-LEVEL TYPE SYSTEM
 
This task force will focus on XML types representing rules and their components, 
as well as on elements belonging to those types. Integration of components to form policies will not be defined by this task 

force.

Current schema reference types:

Complex type TargetType 
Complex type SubjectType 
Complex type ResourceType 
Complex type ActionType 
Simple type EffectType 
Complex type PredicateExpressionType
Complex type PredicateExpressionAbstractType
Complex type PredicateAbstractType
Complex type AndType 
Complex type OrType 
Complex type OrderedOrType 
Complex type NotType 
Complex type PresentType 
Complex type CompareType 

3. TASK FORCE ON OBLIGATIONS

This task force will focus on XML types representing obligations, as well as on elements belonging to those types.

Current schema reference types:

Complex type ObligationsType 
Complex type ObligationType 


4. Task force on XACML IDENTIFIERS
e.g., Requestor, Time of day, Attributes


5. Task FORCE ON XACML EXTENSION POINTS
