Thanks everyone for your comments !
Since there is interest in this topic, I suggest that we have a discussion about where to go from here (create a dedicated group, start writing a specification, find funding, develop an external agent, develop an extension for CSS, etc.)
Here’s a poll to find a slot in January. If none of the proposed slots work for you, please let me know!

Thanks for the reminder, I created a use case here. It is very basic at the moment so feel free to add informations, needs, examples, etc.
