Granularity is a duration that offers some powerful features. Sometimes it means different things. It is not hard to imagine a WS-Calendar artifact that uses Granularity twice.

A) Granularity of Scheduling.. With a granularity of one hour, intervals can only be scheduled one hour apart. But from what?

Base case1: Granularity PT15M, Intervals can be scheduled at 8:00, 8:15, 8:30, 8:45.
Base case2: Granularity PT1H, Intervals can be scheduled at 8:00, 9:00, 10:00, 11:00...
Base case3: Granularity PT1H, Intervals can be scheduled at 8:30, 9:30, 10:30, 11:30...

How do we distringuish between case 2 and case 3?

B) Granularity of Duration.

Base case1: Granularity PT15M, Intervals can be PT15M, PT30M, PT45M,... Is there a mamximum length?

C) How do we distinguish between (A) and (B). Granularity is a propoerty. Properties can be applied to different components. Does the component determine the ontology? WHat are the rules?

D) WHat section of the specification should this be added to?
