CSPACE-4040  ensure consumer may not write uri fields in relations subject/uri and \
  object/uri.  URIs sent to hierarchic authorities will be ignored.  \
  CSPACE-4042  ensures same authority must be used for items related in hierarchy. \
  CSPACE-4037  Service now generates correct REST URIs for all items.  \
  LIST will now return relation-list-item/subject/uri and relation-list-item/object/uri elements correctly. \
  NOTE: removed relation-list-item/service and relation-list-item/documentTypeFromModel from payloads. PLEASE SEE CSPACE-4037 for attached sample payloads from test suite and additional notes.
