[xacml] apr15 schema subcom issues

April 15 2002 schema subcom issues:

 

1. Invesitgate graphical schema representation with 
xml spy (Simon)

    Ann suggested including 
graphical representation of the schema in the core text.

    Everybody is encouraged to get 
schema tools like xml spy or similar.

2. Identity attributes for <Rule> and 
<Policy> (Tim)

    We need to verify that 
<rule> and <policy> elements have identity attributes.

3. list of built-in predicate functions 
(Simon)

    We need to define normative set 
of predicate functions for strings, dates, etc.

4. Attribute designation in the context of 
condition (everybody)

    When attributes are referenced 
in predicate expression within <condition> element it is not

    clear what object owns this 
attribute: subject, resource, environment etc.
