When creating an API Entry Point from a class definition or interface definition, the system relates the existing object type column set to the API Entry Point to display the properties. However, if a column set does not exist for an API Entry Point object type, the system automatically selects the most appropriate column set based on the object type, such as the class definition or class definition's primary interface definition.
By default, the system will always attempt to expose the document version and its
related column set for any document API Entry Point to display the document types,
even if you configure an API Entry Point to expose the revision or master levels.
