My feeling from this thread is that the safe course is this:

The aggregator treats the entityID as non-unique but the combination of the
entityID and the origin location can be treated as unique (for instance the 
xs:ID attribute could be sha1(entityID+origin URL). This means that if an
entity is received from two different "peers" then both are stored by the
aggregator under the same entityID but separate xs:ID. When the entity is
requested by entityID (or hash of same) then the aggregator trust evaluation
decides which entityID to expose.
