Re: asn2wrs AttributeError: Node instance has no attribute 'AddTag'

[lhasa wireshark <lhasawireshark () gmail com>]

Hello Anders,

It seems it can't handle qualified imports like
'OtherModule.TypeDefinedInOtherModule'.

One other problem is that all types are global. If I have 2 different
modules that each defines a type like 'GlobalID' asn2wrs gives an
'Duplicate type' error.

Because the Nokalva compiler works I will presume these are missing
features.  My solution for now is to make sure every typename is unique and
to avoid qualified imports.

Regards,

John
