From http://www.aprs.org/aprs11/tocalls.txt

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.
