If a date in the declassify on line of a classified document containing restricted data and other classified information what additional information should be included in the declassify on line?

In addition to the declassification date, the declassification line should include the authority for declassification, such as the specific executive order or regulation that governs the declassification process. It should also specify the classification level of the document (e.g., Confidential, Secret, Top Secret) and any relevant caveats or handling instructions that apply to the restricted data and other classified information. Lastly, if applicable, it may indicate whether any portions of the document remain classified or if the entire document is now unclassified.
