[db-wg] Out-Of-Region routes ?

My recollection is that there came a time ... I can no longer remember if that was just last year or the year before... when it was decided and implmented that the RIPE DB would no longer allow the addition of route objects for out-of-region address space. Somebody please refresh my memory. At that time, how was it decided that pre-existing route objects for out-of-region IP address locks would be handled? I gather than those were not in fact ejected from the data base, but rather that it was decided... I seem to recall... to simply mark them in some distinctive way. Is that correct? And if so, what was/is that distinctive marking?
