Stefaan,
You are right, it is inconsistent. I would say the example is wrong (I agree
with the direction to always use the name-addr form, it's much clearer).
This is not the only/worst issue with RFC3455 though, consider for example
the P-Charging-Function-Addresses sample :
P-Charging-Function-Addresses: ccf=192.1.1.1; ccf=192.1.1.2;
ecf=192.1.1.3; ecf=192.1.1.4This is
IMHO worse since it violates RFC3261 (using duplicate parameter
names)Regards,Jeroen
