The concepts you defined are for readonly rings. If you check <Geom::Ring const>, it should succeed.

Mutable rings should have clear, resize, push_back too. It is indeed missing in the docs, especially here,
http://www.boost.org/doc/libs/1_54_0/libs/geometry/doc/html/geometry/reference/concepts/concept_ring.html

will be added.
