➢ "Total length of logins/callsigns may not exceed 9 characters including
the SSID if present."
TNC callsigns are 6 plus up to 2 digit SSID and a hyphen. But for anything
else that can also be put on the map as an object or item the field is 9.

The minimum length of any callsign or object/item in APRS is 3 characters.
SSn-N seems to work, Im not sure about how actual hardware digipeaters
handle say Sn-N?
> 5. Is GATE still a valid special handling token worth documenting and
Only a dual Port TNC or other VHF to HF gateway needs to handle it.

Aboslutely not. That would be the worst operating practice. Unless someone
is calling MAYDAY, etc... so leave it in.
