Implements	`osid.OsidSession`
Used By	`osid.provisioning.ProvisioningManager`
Used By	`osid.provisioning.ProvisioningProxyManager`
Description	This session exchanges an existing provision for a request for another provision via the queue. The data for create and update is provided via the `RequestForm`.
Method	getQueueId
Description	Gets the `Queue` `Id` associated with this session.
Return	`osid.id.Id`		the `Queue Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getQueue
Description	Gets the `Queue` associated with this session.
Return	`osid.provisioning.Queue`		the queue
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canCreateRequestsInExchange
Description	Tests if this user can create `Requests`. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a `Request` will result in a `PERMISSION_DENIED`. This is intended as a hint to an application that may opt not to offer create operations to an unauthorized user.
Parameters	`osid.id.Id`	`provisionId`	the `Id` of the provision to exchange
Return	`boolean`		`false` if `Request` creation is not authorized, `true` otherwise

Compliance	`mandatory`		This method must be implemented.
Method	canCreateRequestWithRecordTypesInExchange
Description	Tests if this user can create a single `Request` using the desired record types. While `ProvisioningManager.getRequestRecordTypes()` can be used to examine which records are supported, this method tests which record(s) are required for creating a specific `Request`. Providing an empty array tests if a `Request` can be created with no records.
