Thomas, Inclusion of the following two paragraphs from your email (or similar test) in the draft would address 80% of this concern:
> The SMPTE definition of essence is "The raw video, audio, and data > streams to be contained and described by MXF." (SMPTE 377M) > > SMPTE currently has standards for the mapping of these essence types to > the MXF generic container: MPEG, DV-DIF, Uncompressed Pictures, > SDTI-CP, D-10, D-11, AES3 audio, Broadcast Wave audio, and > A-Law audio. The first paragraph is crucial as the core of my concern is that "essence" is an essentially undefined term in the draft. The examples in the second paragraph are much of what is needed in that area. In addition, I would explain what sort of data streams (non-audio, non-video) are intended to be contained in MXF. Please be sure to expand all acronyms, and explain what they are when that's not clear from the expansion (e.g., D-10, D-11).
