[An option is an alternative set of property-value bindings. Options specify alternative sets of values, typically used in definitions or orders to describe alternatives. An option can only be used as a group, that is, all assigned values must be used together.Historical note: in HL7 v2.x option existed in the special case for alternative medication routes (RXR segment). ( HL7V3.0 )]
