In some logical models, the type of content at one location depends on the value of some other element, and the type is otherwise not explicit in the instance. In such cases, the type of the element is assigned an abstract ancestor type, and this extension specifies how to determine what type is actually used
Context of Use
This extension may be used on the following element(s):
