[Boost-users] [multi_index] - iterator validity?

Hi - I've just started using multi_index. I'm wondering - does multi_index satisfy the same iterator validity constraints as the standard associative containers, i.e: The insert members shall not affect the validity of iterators and references to the container, and the erase members shall invalidate only iterators and references to the erased elements. I *have* looked in the documentation, but haven't been able to find anything which tells me. TIA Stuart Dootson
