In APRS, the AX.25  Destination address is not used for packet 
routing as is normally done in AX.25.  So APRS uses it for two 
things.  The initial APxxxx is used as a group identifier to make 
APRS packets instanantly recognizable on shared channels.  Most 
applicaitons ignore all non APRS packets.  The remaining 4 xxxx
bytes of the field are available to indicate the software version 
number or application.
The AX.25 Destination address is also referred to as the ToCall.  In a humanly-readable (aka TNC-2) APRS packets, this is the characters immediately following the > after the initial source (or originating) callsign-SSID.  Note that for Mic-E compressed packets, the ToCall carries some of the location information bits and not the software identification.

Well, because those notes were accumulated from the changes done over the past 2 years, not necessarily recently.  FT-3D will be in the next update, hopefully later today as I catch up on more stuff.
