 /**

 The CimplementationInformation class acts as the container for the registration 

 data relating to a particular interface implementation.

 Note that this class is used in both the ECOM client and server side hence the 

 mixed API classification seen below. For the client side only the API used to 

 extract the registration data should be used.
