The InstanceInfoData structure contains data related to persistent activations; that is, object activations in which the newly created object is immediately initialized with state from a previously persisted instance of the object. For more information, see [MSDN-COM], [MSDN-SS], and [MSDN-IPersistFile].
CLSID_InstanceInfo (see section 1.9) is used to identify this property in the CustomHeader.pclsid array.
