The LOC may also be an actor in a different profile (DEC DOC, ACM AM, IPEC DOC).  It is highly likely that the Location Observation Consumer (LOC) may also be an observation transaction receiving actor in other IHE PCD profiles.  If the observation is simply to be recorded it is likely to be a DEC DOC or IPEC DOC actor.  If the observation is to be acted upon it is likely to be an ACM AM actor.  If the location observation is to be used for equipment management the LOC actor is likely to be a MEMDMC DMIC actor (a CMMS).
