Janina, Rich, Tzviya, Markus, everybody else,
as you can imagine, some of us had some discussion on this issue during the AC meeting in Paris. I think we are all also eager to move on with this issue as soon as possible. We should also consider the time pressure that the DPUB community has in view of IDPF's plans to move towards an EPUB3.1 version relatively soon.
To facilitate a resolution, I tried to make a (as far as possible, impartial) write-up of the situation we are in and what the available solutions are. I have listed 6 different solution paths, I think we should try to choose one quickly in case my analysis is o.k.
Janina, Rich, I have copied this mail (the text itself is public) to the dpub-aria mailing list; I am not sure what would be the best additional mailing list (if any) where you would want to copy this mail to; feel free to forward this based on your best judgement. I have added Mike and Robin to this mail on the cc list, who know the HTML community but I have not copied this to any HTML WG list; I do not think it is my role to get into the direct PF-HTML Working Group discussions.
It would be good to set up a telco relatively quickly to put an end to this impasse by finding the best possible consensus. I do not think it is realistic to have it this week (although I may be available tomorrow, Friday, afternoon my time in France). Next week I am, unfortunately, at the WWW2015 Conference in Italy but, if you guys agree on a timing for a call, I may try to find a quiet place to join in. The week after the DPUB community gathers in NYC for an IDPF conference, preceded (on Tuesday the 26th) by a F2F meeting of the DPUB IG, ie, that week would probably be out of a question for a call. I must admit I secretly hope that we can put an end to this problem soon (maybe by email?), more specifically by the F2F meeting, but if we do not succeed, then be it.
With that, here is the writeup:

I hope this will help us in moving forward.
Cheers
Ivan
