OSID - osid.offering.rules.OfferingConstrainerEnablerCatalogueAssignmentSession Service Interface Definition

Interface	osid.offering.rules.OfferingConstrainerEnablerCatalogueAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.offering.rules.OfferingRulesManager`
Used By	`osid.offering.rules.OfferingRulesProxyManager`
Description	This session provides methods to re-assign `OfferingConstrainerEnabler` to `Catalogue` mappings. An `OfferingConstrainerEnabler` may appear in multiple `Catalogue` objects and removing the last reference to an `OfferingConstrainerEnabler` is the equivalent of deleting it. Each `Catalogue` may have its own authorizations governing who is allowed to operate on it. Adding a reference of an `OfferingConstrainerEnabler` to another `Catalogue` is not a copy operation (eg: does not change its `Id`).
Method	canAssignOfferingConstrainerEnablers
Description	Tests if this user can alter offering constrainer enabler/catalogue mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known mapping methods in this session will result in a `PERMISSION_DENIED`. This is intended as a hint to an application that may opt not to offer lookup operations to unauthorized users.
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
