For what it's worth, 'cid:' was almost in RFC 1738. Both 'cid:' and
'mid:' exist in RFC 1630. They weren't included in RFC 1738 mainly
because at the time I couldn't figure out what they were good for, I
knew of no implementations, and there were no volunteers to review the
specification of them. All of these conditions no longer hold.

In arriving at new URL schemes, I think RFC 1630 is a good baseline
document: if you change it, have a good reason.
