DMN16 — Missing paragraph break and new constraintType

The below text was a separate paragraph in DMN 1.4. In DMN 1.5 is a part of the previous paragraph. Also, the new typeConstraint property is missing.

An alternative way to define an instance of ItemDefinition is as a composition of ItemDefinition elements. An instance of ItemDefinition may contain zero or more itemComponent, which are themselves ItemDefinitions. Each itemComponent in turn may be defined by either a typeRef and allowedValues or a nested itemComponent. In this way, complex types may be defined within DMN. The name of an itemComponent (nested ItemDefinition) must be unique within its containing ItemDefinition or itemComponent.
