GXDLMSIECLocalPortSetup password 1, password 2, password 5

Hello Mikko,

As written in GXDLMSIECLocalPortSetup definition,

/// Password 1 according to IEC 62056-21.
/// Password 2 according to IEC 62056-21.
/// Password W5 reserved for national applications.

I read IEC 62056-21 and search over it, still can't find any cases of Password 1, 2 ,W5

There is one place C.4.7.2 Parameter data examples where password (from 1 to 8) mentioned (quoted below), but I can't see any connection with three password in class definition.
Don't you know what these password 1, password 2, password 5/W5 are intended for?
