AsnEnumerated

    class AsnEnumerated(AsnComplexNode)
       This class stores the semantic content of an ASN.1 enumeration.
       Members:
           _name : the name of the type
           _isOptional : if True, node is optional
           _members : a tuple of all the allowed values for the enumeration.
                      Each value is itself a tuple, containing the name
                      and the integer value associated with it (or None,
                      if it is ommited)
           _default : if one of the values of the enumeration is the default,
                      it is contained in this member
