[Uri-review] Request for review of "ab:" URI scheme

[Barry Leiba <[e-mail]>]

In the Sieve working group, draft-ietf-sieve-external-lists defines an
address-book URI scheme, "ab:".  See the draft, here:
http://tools.ietf.org/html/draft-ietf-sieve-external-lists

We would like to get uri-review comments on the proposed scheme.
There's a reference to the scheme in section 2.5, it's used in the
examples in section 2.8.1 and at the end of the Security
Considerations (section 3), and it's defined and registered in section
4.3.

Thanks in advance for reviews and comments.

Barry
