This is the verdict of the duplicate-identifier check: whether a genuine collision was found. It's what UCS Central writes back after evaluating a Scope request, telling the operator whether an actual naming or ID collision was found so the merge or registration can be blocked or allowed to proceed. Values are drawn from a small status enumeration such as 'ok' versus 'duplicate-found'; the latter is what blocks a domain registration or merge from UCS Central until the naming conflict is resolved by hand.
