D.2 Ranges and the Palo Alto TR (N3351) [diff.n3351]

D.2.5 Output Iterators [diff.n3351.output_iters]

The Palo Alto report does not define concepts for output iterators, making do with WeaklyIncrementable, Writable, and (where needed) EqualityComparable. The author of this document sees little downside to grouping these into the familiar OutputIterator concept. Even if not strictly needed, its absence would be surprising.
