It might be best to inform your PM that development plans and development standards are usually originated by key members of the project team along with input from the customer. If you were furnished these documents, there is not a good chance that they would apply to your organization. If your PM needs clarification and understanding, please invite them to establish a dialog here.
I would also talk to your project manager and ask if he/she has an example of this document. From what you have described I would usually consider this to be something that was a standard part of the SDLC - at the very worst developed by the PM for a project.
