I think this is semantics, you cannot do it in the TNC because the TNC conforms
to the AX-25 spec, you are both right...

And Bob, remember not to quote the APRS spec on matters involving the APRS
Internet System, the APRS spec explicitly does not cover the APRS IS. The plan
was to do the APRS IS as a separate document, but no one had the stamina to
tackle it after the first spec was finally completed. On the air, the protocol
is obviously limited by the 6 char + 4 bit ssid limit of the AX-25 spec. On the
internet, you, Pete, and I have three different assumptions about what is
permissible, so obviously there is not absolute answer...
