Sets/gets the name identifier which will be used
to pass the context between the objects in the composite.
The context name should be set before any objects are added to the
composite. The name takes effect when the object is added so changing
the property will not change the context name of the already added
objects. To avoid mistakes avoid changing the context's name during
the composite management.
How the context name is used:
If the object is a script the context (VaryDispCtx
object) is visible to the script as global namespace with the
If the object is an ordinary COM object a method with this name
will be called with one parameter - the VaryDispCtx object. So if the
COM object is especially written for usage in composites it will be
able to record and use it further.
