Is read_committed_snapshot dependent on allow_snapshot_isolation? I thought the latter had to be on before you could use the first. This article seems to indicate so but I'm not sure.

I tried setting read_committed_snapshot to ON while leaving allow_snapshot_isolation set to OFF and I did not get an error as I expected.
Perhaps I misunderstood the above article?
