+ queries once per day to domains for which trust anchors

+<p>
+ The query name used for these queries has the
+ form "_ta-xxxx(-xxxx)(...)".<domain>, where
+ each "xxxx" is a group of four hexadecimal digits
+ representing the key ID of a trusted DNSSEC key.
+ The key IDs for each domain are sorted smallest
+ to largest prior to encoding. The query type is NULL.
+ </p>
+<p>
+ By monitoring these queries, zone operators will
+ be able to see which resolvers have been updated to
+ trust a new key; this may help them decide when it
+ is safe to remove an old one.
