Interface	osid.ordering.rules.PriceEnablerRuleLookupSession
Implements	`osid.OsidSession`
Description	This session provides methods to retrieve `PriceEnabler` to `Price` mappings. A `Price` with multiple `PriceEnablers` means any positive rule evaluation across the enablers result in an effective `Price.` This lookup session defines several views: comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete result set or is an error condition isolated store view: All methods in this session operate, retrieve and pertain price enablers defined explicitly in the current store federated store view: All methods in this session operate, retrieve and pertain to all price enablers defined in this store and any other price enablers implicitly available in this store through store inheritence.

Compliance	`mandatory`		This method is must be implemented.
