WPD open access model

Question

 I try to implement the open access model in my WPD device.

But unfortunately the _WPD_CLASS_EXTENSION_SERVICE_ACCESS_MODEL_TYPES Enum doesn't defined in the PortableDevice.h.

Another problem is the definition of WPD_COMMAND_CLASS_EXTENSION_REGISTER_SERVICE_INTERFACES that defined to get only 2 parameters instead of 3. (The optional parameter WPD_PROPERTY_CLASS_EXTENSION_SERVICE_ACCESS_MODEL is missing).

I checked it on Win8 RTM with the latest Visual Studio 2012.

Where is my mistake?

Thanks a lot.
