Adding References to other Value Sets

As described earlier, value sets can also reference other value sets. One way to establish this sort of reference was the underValueSet element of createValueSet. This mechanism, which was described previously, created a reference from an existing value set to a newly created set. A second way to create value set references is through the addValueSetReference element. addValueSetReference elements may occur under both the value set creation (createValueSet) and value set modification (selectValueSet) nodes.

Element addValueSetReference

Each addValueSetReference entry can include an optional ballot status which, if present, overrides any outer ballot status entry. addValueSetReference consists of one or more listEntry, each of which names a value set to be added to the current value set being created or modified.

Attributes of listEntry

setName	The name of the value set to reference.
setType	One of abstract or specializable. Abstract means that the head code of setName (if any) is not included as part of the value set being defined. Specializable means that the head code (if any) is to be included.

Example XML for addValueSetReferences

The above example creates a value set named “OrderableBeers”, which is composed of two other value sets – “SpecificAles” and “SpecificStouts”. The head code for SpecificAles is not included in the value set, while the head code for SpecificStouts is.
