8.51 StructureField

NodeId of the DataType for the field. When used by a StructureDefinition with a structureType of Structure, StructureWithOptionalFields or Union then the datatype shall be a concrete DataType , BaseDataType DataType ... Structure DataType If the structureType is StructureWithSubtypedValues , or UnionWithSubtypedValues and the isOptional field is TRUE then the encoding of the field shall be able to transport any subtype

5.1.7 Structures and Unions

adding additional name-value pairs to the sequence. If a DataTypeDefinition sets the StructureType to StructureWithSubtypedValues then any field with a subtype of Structure DataType and IsOptional =TRUE allows ... possible to add an AllowSubtypes flag to StructureField and preserve backward compatibility. The value StructureType indicates how the IsOptional field is to be interpreted. A field is serialized
