#### 5.2.8.4 Concept Domains

Concept Domains (see definition in Section 3.2) are used to provide a named category in a structural template that can be bound to a specific value or value set by an invoking template, thus specializing the structural template for a particular use case. Concept Domain names are introduced by the keyword ConceptDomain in the Value column. For example, the 10.5 Quantity Measurement template Concept Domain "observationType" might be bound to a value set of fetal ultrasound measurements in one invoking template, or to a value set of cardiac CT measurements in another invoking template.

Concept Domain names are similar to element Business Names in that they provide a public interface that is bound to specific values later in the document specification and production process. Concept Domains do not have a Value Conformance verb; the conformance verb is specified when the Concept Domain is bound to a specific value or value set (see Section 5.2.9.1).
