Rodrigo,

Thanks for your comments. As Joe pointed out,
some of them are resolved in the latest version (06).

EAP SIM  and EAP AKA have essentially the same identity
format, expect for the leading character. So the leading
character could actually save protocol messages because
it can be used as a hint of which one of these two EAP
types the client wants to use. For an example scenario
where roundtrips could be saved is a UMTS
subscriber whose terminal only implements EAP SIM.=20
