[aprssig] Using SSID's outside 0 to 15

I understand that there is an AX.25 limitation that restricts 
conventional APRS using 1200 bd AX.25 to SSID's of 0 to 15.

Using the APRS over PSK-63 system in APRS Messenger there is no 
restriction and something like G4HYG-HF goes through the APRS-IS and can 
be viewed on aprs.fi and APRS clients OK. See: 
http://aprs.fi/info/?call=G4HYG-HF

If SSID'd outside the 0 - 16 range were to be used regularly would this 
cause a problem? I know D-Star uses some alphanumeric SSID's over the 
APRS-IS so am I right in thinking probably not?

73,

Chris, G4HYG
