Hello. You cannot add new matter to a patent application. You can remove material or make minoir edits to the Spec, but you cannot submit a new Spec that includes new matter not in the original. To add to, or expand upon, an existing patent application, you will need to file a Continuation application, which is a separate & new application that claims priority to the original patent. Normally, with a restriction/election requirement, you just need to elect your claims and remove the rest (un-elected claims)....then you can file a continuation patent where you pursue the un-elected claims.
let me know if you need clarification
that being said, there is no special language, you just say that you are "submitting a substitute specification that replaces the current specification"
