                        A contraindication is just a negation of a reason, i.e. it gives
               a condition under which the action is not to be done. Both, source and target can be any
               kind of service; target service is in criterion mood. How the strength of a contraindication
               is expressed (e.g., relative, absolute) is left as an open issue. The priorityNumber attribute
               could be used.

                           Description: The reason or rationale for a service. A reason
               link is weaker than a trigger, it only suggests that some service may be or might have
               been a reason for some action, but not that this reason requires/required the action to
               be taken. Also, as opposed to the trigger, there is no strong timely relation between
               the reason and the action.  As well as providing various types of information about the
               rationale for a service, the RSON act relationship is routinely used between a SBADM act
               and an OBS act to describe the indication for use of a medication.  Child concepts may
               be used to describe types of indication.

                           Discussion: In prior releases, the code &quot;SUGG&quot; (suggests)
               was expressed as &quot;an inversion of the reason link.&quot; That code has been retired
               in favor of the inversion indicator that is an attribute of ActRelationship.

               incidents where potential harm could have occurred, but the action described in the source
               act blocked the potential harmful effects of the incident actually occurring.

                           Rationale: There is a need when defining a clinical trial protocol
               to indicate that the protocol makes use of other protocol or treatment specifications.
                This is stronger than the assertion of &quot;references&quot;.  References may exist
               without usage, and in a clinical trial protocol is common to assert both: what other specifications
               does this trial use and what other specifications does it merely reference.

                        The source act thus is a specialization of the target act, but

                        The typical use case is to specify certain alternative variants

               over other alternative refinements.

               routing options.

                        Example: A posted financial transaction (e.g., a debit transaction)

               act is EVN the source act can be EVN, or any INT. If the target act is INT, the source
               act can be INT.

               marking the approximate area.  For example, if the start and end of an ST elevation episode

               observation -- the ROI defines the true beginning and ending of the episode.  Conversely,
               if a ROI simply contains ST elevation, but it does not define the bounds (start and end)
               of the episode, the more general &quot;has support&quot; relation is used.  Likewise,
               if a ROI on an image defines the true bounds of a &quot;1st degree burn&quot;, the relation
               &quot;has bounded support&quot; is used; but if the ROI only points to the approximate
               area of the burn, the general &quot;has support&quot; relation is used.

                           FormalConstraint: Source Act must be an Observation or specialization
               there-of. Source Act must not have the value attribute specified
            <br/>

                        
                           UsageNote: This relationship allows the result of an observation
               to be fully expressed as RIM acts as opposed to being embedded in the value attribute.
                For example, sending a Document act as the result of an imaging observation, sending
               a list of Procedures and/or other acts as the result of a medical history observation.
            <br/>

                        The valueNegationInd attribute on the source Act has the same
               semantics of &quot;negated finding&quot; when it applies to the target of a VALUE ActRelationship
               as it does to the value attribute.  On the other hand, if the ActRelationship.negationInd
               is true for a VALUE ActRelationship, that means the specified observation does not have
               the indicated value but does not imply a negated finding.  Because the semantics are extremely
               close, it is recommended that Observation.valueNegationInd be used, not ActRelationship.negationInd.
