Names in parenthesis for the operations, status codes, or attribute tags are for abandoned values. For example, the Send-Notifications operation was part of the ipp-indp-method draft that was never advanced. Since we never re-use enumeration values, that operation code will always be "Send-Notifications" and we want to be able to report that.  The corresponding C enum constants are marked private for purposes of documentation...
