Allow files that are protected to be attached to other documents, but still not be allowed to be edited
I have clients that want to attach my drawings to their pdfs but I protect my drawings from editing. They want me to unprotect them and allow editing. I do not want to do that. I would like adobe to have a security feature where you allow attaching to other documents but you do not allow editing the document that is already protected. Clients are very angry that I wont give them the password.
