CUID uniqueness 1

[xxyyzz49]

The quote below is from a white paper titled "Business Views Security" found at this Business Objects link. My question is are CUID unique generally or just locally? I ask because the explanation below after carefully stating that CUID are unique locally to a cluster and then unique to other clusters undid all that explanation by writing CUID are:

unique to each CMS/cluster and they don't change.

Unique to a cluster implies locally unique but not generally unique by my reading.

A CUID is a string that uniquely identifies an Object within a CMS/cluster. No two objects in a CMS/cluster have the same CUID. There won’t be two objects in two independent CMS/cluster that would have the same CUID. Objects refer to each other by CUID rather than Object ID, because CUIDS are unique to each CMS/cluster and they don’t change (i.e. CUIDS stay the same when importing objects from one CMS/cluster to another)

I can't give you an authoritative answer on this, but I will point out that being unique across clusters doesn't contradict the first statement. It only contradicts what you see as implied. A universally unique CUID will still uniquely identify an object within a cluster. And they explicitly state that CUIDs stay the same when imported into another cluster. That can only work when they are universally unique.
