Your example doesn't work since foreign AOC holder employees are not covered by DAMP.

The problem with exempting employee categories is that once they are exempt they are restricted in where they can go due to the definition of SSAA including the bracketed statement of "by their presence". I take that to mean that if you are in a SSAA for any purpose ie letting someone know that there is a phone call, that they are deemed to be testable.
