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

Interface	osid.offering.rules.OfferingConstrainerCatalogueAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `OfferingConstrainer` to `Catalogue` mappings. An `OfferingConstrainer` may appear in multiple `Catalogue` objects and removing the last reference to an `OfferingConstrainer` 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 `OfferingConstrainer` to another `Catalogue` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignOfferingConstrainers
Description	Tests if this user can alter offering constrainer/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.
