Mike's text works for me too. Once I get Guus's approval/edits on my proposed wording for Reference, I'll incorporate everything into a revised proposed response to Jen. I also have Dave Beckett's imports comment to deal with. It mentions the same changes to Reference that I am awaiting for Guus to look at. Assuming he is OK with these or has minor changes, can I send that response once I hear from him? (Jim, I know you've already approved that response, so this question is really more directed at Guus and Dan).
