| This attribute is an identifier reference to a specific element within the stream. It is recommended that whenever possible this element is used to reference the specific data that is the source of this extended status. Reference multiple unrelated data elements by repeating the entire ExtendedStatus aggregate. If the cause of the extended status is relational in nature then a single ExtendedStatus should reference all of the related data elements. A description of the underlying relational cause can be put in ExtendedStatusDesc |
