Non-US classification portion marking for foreign government information in a document portion. Use this attribute to record a source country when the intent is to filter out the identity of the source prior to posting the document to a shared space.

If "25X1-human" applies, it should be first in a list. One or more tokens indicating that a source that is exempted from automatic declassification applies. Specify "OADR", "X1", "X2", ..., "X8".
