OSID - osid.assessment.authoring.AssessmentPartItemSession Service Interface Definition

Interface	osid.assessment.authoring.AssessmentPartItemSession
Implements	`osid.OsidSession`
Description	This session defines methods for looking up `Item` to `AssessmentPart` mappings. 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 assessment part view: only items in the specified assessment part are accessible federated assessment part view: includes items in assessment parts that are descendants of the specified assessment part The methods `useFederatedAssessmentPartView()` and `useIsolatedAssessmentPartView()` behave as a radio group and one should be selected before invoking any lookup methods.

Compliance	`mandatory`		This method is must be implemented.
Method	getAssessmentPartItems
Description	Gets the list of items mapped to the given `AssessmentPart.` In plenary mode, the returned list contains all known items or an error results. Otherwise, the returned list may contain only those items that are accessible through this session.
