public ref class ParameterElement : public Element

Revit supports both built-in and user-defined parameters. Built-in parameters ship with the application, and they are not stored in Revit documents. User-defined parameters are dynamically created, and they are stored in the documents that use them, wrapped in ParameterElement objects. Different subclasses of ParemeterElement represent different kinds of user-defined parameters.
