I’ve merged the change into the master branch. Dave had a concern that it supports framing signatures using named graphs, which it should. We can add additional test cases in a separate PR.

Within a sub-frame, the use of @graph will cause framing to occur based on the name of the subject of the nodes that match that frame.
