Hi Kevin,

This is the intentional behavior for the feed's element <updated>, the
idea is to set a snapshot reference for you to use in future queries.
For example, if you send a request for a feed and keep track of the
value of the feed's <updated> element. Then you can later retrieve
only the contacts that have changed since the previous request by
setting updated-min to that <updated> value.

Cheers,
Julian.
