      Policy Expression Requirements - Policy Expression Pattern

      We really need to make an effort to better explain this section. I suggest that before laying out the exact pattern, we describe the approach in layman's terms. How about something like this:

      [Place at the top of Policy Expression Pattern]
      A policy is the combination of individual policy statements. An XDI policy statement can take two forms:

      • A condition that must be met or,
      • An authorized operation that may only be performed over a particular XDI statement (or subgraph?).

      A condition is described using a <context> / <value> / <condition> patten where:

      • <context> describes the relationship of this statement to other statements
        in the policy (i.e. how to compose those statements)
      • <value> is the boolean value the condition must match
      • <condition> describes the condition to be evaluated by the policy

      An authorized operation is described using a <context> / <operator> / <XDI subgraph> pattern where:

      • <context> describes the relationship of this statement to other statements
        in the policy (i.e. how to compose those statements)
      • <operator> describes the graph operation that is requested
      • <XDI subgraph> describes the targeted XDI statement (or subgraph)

      In details, /.../ <== At this point, we can add the formal pattern description that’s already in the spec. However, I would recommend keeping the separation between the 2 types (condition & authorized operation) and align the terminology with the above.
