    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?
    
    
    Rgds

    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
