Comment (by jinmei):

 Replying to [ticket:2613 muks]:
 > Make RRsetCollectionBase iterator implementation compatible with Boost
 foreach. Currently it has a basic forward iterator implementation.

 What's the specific requirement?  I suspect it's not feasible (at
 least quite difficult) to make it bidirectional iterator for DB-based
 data sources.
