ORD Cross Section Frame Annotation

What is the intent of "frame" annotations under the cross section annotation group dialog? I have found limited help for the dialog, but I would imagine they can annotate the same points as a "point" annotation definitions yet locate them along the frame rather than at the points within the cross sections. If so, I am having trouble getting a text favorite to carry intelligence. If I want to annotate offset/elevations along the frame, shouldn't my OpenRoads Designer Cross Annotation Field for point offset/elevations work here?
