Change the following descriptions:{ } ConceptMap.group.element.valueSet Definition: The set of concepts from the ConceptMap.group.source code system which are all being mapped to the target as part of this mapping rule.  Short display:   Identifies the set of concepts being mapped. Comment: If the value set expansion is empty then there are no source concepts to map in this rule.   ConceptMap.group.element.target.valueSet Definition: The set of concepts from the ConceptMap.group.target code system which are all being mapped to as part of this mapping rule. The effect of using this data element is the same as having multiple ConceptMap.group.element.target elements with one for each concept in the ConceptMap.group.element.target.valueSet value set. Short display: Identifies the set of target concepts. * Comment: * If the the value set expansion is empty then the source concept(s) are unmapped and the behavior of ConceptMap.group.unmapped (if present) applies.   * ConceptMap.group.unmapped * * Definition: * What to do when there is no mapping to a target concept from the source concept and ConceptMap.group.element.noMap is not true. This provides the "default" to be applied when there is no target concept mapping specified or the expansion of ConceptMap.group.element.target.valueSet is empty.  * Short display: * What to do when there is no mapping target for the source concept and ConceptMap.group.element.noMap is not true. * Comment: * The 'unmapped' element is ignored if a code is specified to have relationship = not-related-to or if ConceptMap.group.element.noMap = true.    ConceptMap.group.element.noMap Definition: If noMap = true this indicates that no mapping to a target concept exists for this source concept.  Short display: No mapping to a target concept for this source concept. Comment:   If noMap = true, then the behavior of ConceptMap.group.unmapped (if present) does not apply.
