I would be inclined to drag up. However, if I could not for some unknown reason, I would have to perform a code reconciliation that included all the varying referenced specs and documents.
In effect, the only way to make them all happy would be take each point on a point by point basis and utilize the most stringent criteria.
I am unaware of any code, specification, or other criteria that prohibits a more stringent approach. That would be the only safe path forward that I can see. Then again, it would not be the first time I have told someone to pack sand when they refused to give me the information I needed to be successful. I don't take being set up for failure as you are being very well.
