9.1.2.1.1 Message ID

This parameter identifies the operation. It is used to distinguish this operation from other notifications or operations that the DIMSE-service-provider may have in progress. No two identical values for the Message ID (0000,0110) shall be used for outstanding operations or notifications.

Notes: 1. Inclusion of this parameter in the confirmation was permitted in previous versions of this Standard but this mode of use is now retired. This parameter may be included in the confirmation but in such a case the invoking DIMSE-service-user should not attach any semantic significance to this parameter.

2. The Message ID (0000,0110) is recommended to be unique within the scope of an Association, to support debug procedures.
