Thanks for those links Xiaoming!

I have added them to the See Also of uid-brainstorming:

http://microformats.org/wiki/uid-brainstorming

(by churning away, I only mean that there are both several unique abstract
id schemes already, as documented by the above urls, and that we're likely
to see more in the future.)

True.  My point is that URL is preferable over URN as well, and thus we
prefer to say that UIDs SHOULD be URLs, though certainly per your point we
could say if you cannot use a URL for your UID then you SHOULD at least use
a URI/URN.

Or are you proposing that we say that UIDs MUST be URIs in the context of
microformats?

Thanks,
