Dear Jens,

Thank you so much for your extensive suggestions - they're extremely
useful and productive. It's going to take the MODS Editorial Committee a
bit of time to parse through all of this, so we appreciate your patience.
We'll follow up on list shortly. In the meantime, any other thoughts from
others in the community on these issues would be most welcome.
