I don't know exactly why I joined this list. MICE isn't OIX certified or anything. But since I got this and read it, I figured I'd pass along these comments.

Some notes, in the order they appear in the document. Most of these are typographical. The ones that are more than typographical are in bold.

Page 7 has musts and shoulds that are not all caps and bold like the rest.
$100,000 as a maximum annual revenue for "community supported" excludes MICE. And yet, the revenue that MICE takes in just barely covers replacing the switching infrastructure every few years as needed. We are still relying on donated labor, etc. I'm not sure what "community supported" status means, so maybe this doesn't matter.
Physical Interface: There is a "MUST not". You should search for those and make them all "MUST NOT" and bold.
Physical Interface:I'm not sure why you disallow speed negotiation. If an IX is offering copper, what is wrong with that? (I have no dog in this fight. MICE doesn't and I don't personally care.)
Physical Interface: Not requiring any specific Ethernet speed is good. I saw some comments today from people who said that requiring 1G was a problem for them.
Route Server: "a unique" was correct; the change "an unique" is wrong.
Route Server: 2 should start with "That" and "IP" should be capitalized.
Route Server: 3 should probably remove the second "that", add a comma, and s/onto/to/, so it reads "‭That rather than honoring the NO-EXPORT community, it ‬‭MUST‬‭ pass that‬ ‭community to the connected member / participant."
Route Server: In 4, capitalize ip, add periods at the end of "d", "e", and "i(i)".
Route Server: In "4(i)(ii)", I think "black holing" should be one word.
Route Server: editing errors in the "MUST publish the route server setup" bit, specifically "on a website available". It was probably fine as written originally, "on a publicly available website" which matches everything else like that.
You give a sample ACL for BGP culling, but is that actually listed as a requirement anywhere? It should be at least a SHOULD to use that for maintenance.
