Selection names (as seen by the client) are internally prefixed with the
namespace ID, so each client can only access those within it's namespace.
If a client within namespace "foo" want's to operate on "PRIMARY",
it actually will be doing so on "<foo>PRIMARY", w/o ever noticing it.
Events will sent back to the client still pointing to "PRIMARY".
