I know that....I want to know what the pay part of that means.
You are right. I was having fun and yet not answering your question.
The Classification Act of 1923

It seems the ACT was to clarify the meaning of “employee”, “service”, and “compensation”, in regards to civilian positions within the District of Columbia and in the field services.
READING BETWEEN THE LINES, of the HC Resolution Bill pertaining to your question, it could be a way for the President to ‘EMPLOY’ NON-AMERICAN citizens.
It could be a way of saying that pay scales like the GS classification used in Federal Service WILL NOT APPLY to the Doctor’s Corpse.
Read it and see what you think.
