Re: [poe] isNeccessaryFor

1) *All* constraints need to be checked at the time of exercising the 
action. So why are the Constraint Relations any different?

2) We define what happens if there is no result of a constraint in the
 Perm/Pro/Duty sections:
"Constraint: the Permission may refer to one or more Constraints which
 affect the validity of the Permission - it only becomes effective if 
all of the referred Constraints are true "

3) We define "satisfied" in the first para of the section: "If the 
logical expression evaluates to true, the result of the Constraint is 
satisfied."

4) "C1 odrl:isNeccessaryFor C2": first: why "both MUST be satisfied"
The both needs to be satisfied (since its also an "and" 
relationship)...then it goes on and says that C1 is "done" before C2 
is processed.

5) If a result cannot be generated, then a result cannot be generated.
If the constraint is "event = end-of-the-world" then it won't be 
satisfied...ever ;-)
This is something we cannot address.

6) Syntax errors are not our problem.
