You're right. That was exactly what we wanted at Hamburg.

And the resolution at Hamburg actually helped, although it may not make WD now. By that resolution, authors understood something more stable and usable is coming soon. Implementers understood it's something worth to spend time on. Access, a Japanese implementer, actually created a patch and is going to upstream to Readium, and is also seeking for a possibility to upstream WebKit too. I'm not sure if they can make it or not, but yes, that was what I wanted, and the resolution at CSS WG helped it to happen.

It was exactly where Japanese authors and implementers were before Hamburg. Thank you for explaining that in clean words.

Now that both authors and implementers are aligned to draft #5.5 thanks to the resolution and thanks to a lot of work to make it, and draft #6 is in the horizon, Sylvain's proposal makes great sense to me now.
