[aprssig] Digi "Location-Based" Callsigns and Objects

Being objects you don't have to do anything differently than you are
doing now. The originating station of course has to identify as usual,
so if you are using a tactical callsign common practice is to put your
legal callsign in the comment of the station's own beacons. As long as
one of these is sent every 10 minutes, the station is legally
identified for all packets being transmitted whether they are
digipeated positions from other stations or objects sourced from

The source callsign of an object should be the actual on-air callsign
of the originating station in most cases. In your situation why would
you feel the objects need to be sourced from your callsign while being
originated from the digipeater?
