docs: <p>This method will compare the passed in set of localising ME uuids with the
  set already known about.  If there are any new localising ME's the infrastructure
  to be able to send messages to them is created.  If the ME knows about some
  that are not in WCCM, they are marked for deletion.  If they are still being
  advertised in WLM, nothing more is done until they are removed from WLM as
  WLM can still return them as places to send messages too.  If the entries are
  not in WLM, an attempt is made to rejig the messages.  This will move them
  to another localisation if possible, or will put them to the exception destination
  or discard them.  If after the rejig, there are no messages left awaiting
  transmission to the deleted localisation, the infrastructure for the localistion
  is removed, otherwise it is left until the last message has been processed.</p>
