The dynamic Assembly instance must be instantiated with a call to the class
level Create service. Then the structure can be defined with the
Set_Attribute_Single service for the Member List attribute. Only one dynamic
Attribute instance is supported so subsequent calls to the Create service will
return a Resource Unavailable (0x02) error. The Delete service can be used to
destroy the dynamic Assembly instance so that it can be re-created.
