Is there some reason why there are THE3GPP_SGSN_ADDRESS and 
THE3GPP_GGSN_ADDRESS type values, rather than just making those TLV's 
have the type RADIUS_IP_ADDRESS?  (That enum isn't supposed to be an 
enum of every single attribute, it's supposed to be an enum of 
attribute types.)

Similarly, perhaps there should be a RADIUS_UTF8_STRING type for all 
the UTF-8 strings and a RADIUS_IPV6_ADDRESS type for IPv6 addresses.

Also, THE3GPP_CHARGING_ID is just like RADIUS_INTEGER4 except that it's 
printed with "%d" rather than "%u" - is it really a *signed* 32-bit 
integer?  If not, it should probably just be RADIUS_INTEGER4.
