COMMENT:
----------------------------------------------------------------------

I'd like to begin by noting that I know basically nothing about SMPTE or ST 291
or Ancillary Data. I opened the document thinking that this was going to be
either impenetrable, a huge waste of my time, or both...

I was very pleasantly surprised by how clear, accessible and interesting the
document is -- it clearly describes the use case / problem, provides just
enough background to make understanding the discussion (relatively) easy, and
documents the solution / protocol in a clear and concise manner.

I'm not really qualified to evaluate if this is the best way to implement / if
it has hidden landmines (see first sentence!), but I'd like to thank the author
and WG for producing a document which was a pleasure to read.

I'd also like to draw your attention to Nevil's OpsDir review, which contains
some good questions, and some nits:
