Document to which the created element will be added
definition_id String
ID of the shape definition that was created earlier and stored via DirectShapeLibrary

IList GeometryObject
A collection of GeometryObjects representing a placed instance of the pre-defined shape The caller function takes ownership

Remarks
Use DirectShapeLibrary class to store definitions prior to using them here. How the definitions are stored will determine whether an instance or a copy of the shape will be created.
