The WAVEDescriptor::Summary property should contain
the WAVE header, i.e. the WAVE file minus the audio
It is not clear (currently) whether the WAVE data chunk
should be missing altogether from the Summary or
present but minus the audio samples.
CAAFWaveCodec::CreateWAVEheader does the former,
a well-known shipping AAF implemention does the latter
and expects it on import.
The AAF Engineering group need to decide what is
correct and update the SDK codec appropriately.
