Review Comment:
Not totally happy with that yet, as
1. distinction between PARENTED and STANDALONE could be more explicit
(separate methods)
2. column-order-txt feature supports identifier wildcards, which could be
reflected by leaving the memberId empty here
(same applies to the next method below)
