Thanks for this really interesting reading!
I have some comments and I plan to write them in different e-mails, thus
starting different threads on the MaRC list.
In this e-mail, I would like to ask whether some work is ongoing to reflect
about the implications of the introduction of these MaRC improvements into
MODS. I consider it is important to try to ensure that the chosen design will
work fine when it is introduced into MODS.
