[OR] Can the Excel/Element Template XML Utility developed for ORD be used with earlier versions?

I just watched some of the videos in the series OpenRoads Designer Workspace Setup Learning Path on the Learn Server. I was encouraged to see the capabilities of bulk editing of Feature Definitions, Symbologies and Element Templates. Tools like this are real huge time savers for CADD Management.

While we are pretty far away from migrating to ORD, I was wondering is the format of the Element Template XML file that the Element Template <-> Excel tool uses is compatible with Ss2/Ss3/Ss4?

I eagerly await a response.
