A terminology binding that represents the set of permitted values that can be used to populate a coded data item.
A value set binding can be defined using individual rules. For example concepts that are: in a list of included concept identifiers, members of a specified reference set or subtypes of a specified concept.
Expression constraints provide a more flexible way to represent value set bindings as they are able to represent and combine a range of different rules to determine the set of concepts or expressions that are part of a value set.
