  It should be noted that all interactions are assumed to be synchronous, with the exception of Notify Registry Event. This document is sent by the SDMX-RR to all subscribers whenever an even occurs to which any users have subscribed. Thus, it does not conform to the request-response pattern, because it is inherently asynchronous.

++__Actual object is contained in a maintained object with no intermediate containing object but the object type itself is hierarchical__
  In this case the object id may not be unique in itself but only within the context of the hierarchy. In the general syntax of the URN all intermediary objects in the structure (with the exception, of course, of the maintained object) are shown as a contained object. An example here would be a Category in a Category Scheme. The Category is hierarchical and all intermediate Categories are shown as a contained object. The example below shows the generic structure for Category Scheme/Category/Category

++__Actual object is contained in a maintained object with an intermediate containing object and the object type itself is hierarchical__
  In this case the generic syntax is the same as for the example above as the parent object is regarded as a containing object, even if it is of the same type. An example here is a Metadata Attribute where the contained objects are Report Structure (first contained object id) and Metadata Attribute (subsequent contained object Ids). The example below shows the generic structure for MSD/Report Structure/Metadata Attribute/Metadata Attribute
