involved with. The remarks block may explain how the DID will be applied, but can not alter or add to the DID. (Language altering the data item description would obviously make it no longer a standard DID available by simple citation, pre-approved, and readily handled by existing Department of Defense processes.) Contracts issued by governments (including their militaries) outside the US also use CDRLs as part of their statements of Work. These CDRLs do not use the US military's DD Form 1423, but may utilize some of the same elements to define their need for documentation.
