This code system http://hl7.org/fhir/map-target-list-mode defines the following codes:

Code | Display | Definition
first | First | when the target list is being assembled, the items for this rule go first. If more than one rule defines a first item (for a given instance of mapping) then this is an error.
share | Share | the target instance is shared with the target instances generated by another rule (up to the first common n items, then create new ones).
last | Last | when the target list is being assembled, the items for this rule go last. If more than one rule defines a last item (for a given instance of mapping) then this is an error.
single | single | the target instance is shared with a number of target instances generated by another rule (up to the first common n items, then create new ones).
