Nope, but it's a good start.  If I receive a header from an AEA TNC
(which has a different order for the SRC/DEST/PATH elements than a
TAPR-2 TNC does), I just pass it on to the APRS-IS.  Same for
wherever the TNC decides to place one or more asterisk characters, I
just pass them on.  So...  Anything receiving packets off the
APRS-IS has to be able to decode these variants.
