Re: merging media overlays

I wonder how it would work with the future of Sync Media [1], which is looking more and more like an evolution of MO - would having a merged EPUB + MO slow us down in the future if we wanted to incorporate these ideas into a future (beyond 3.3) MO spec?

The fact it was assigned a core 3.X incrementing number does make it stick out if not incorporated, but more usefully it just harmonizes things like the schema and vocabulary definitions together, and doesn’t require cross-referencing all the terminology.

But maybe that’s part of what we need to fix in terms of testing, too.
