[mediaqueries] Add epub/page to media queries list?

Hi

I am wondering are we able to add epub/page to media queries list?

I have read mediaquies-4 but can not find any of them is proper for a displaying(on screen, not printer) paginate media
http://www.w3.org/TR/mediaqueries-4


The requirement is because
1. dynamic: it’s for displaying on screen, not printer, such as epub reading system (RS) which is based on web browser rendering engine. So, javascript, animation should can work on this media type.
2. pagination: it still needs a paginated layout to enable like break-before/after on screen, instead of printer preview.
3. some css might be more proper for continues displaying not paged media.

Just a rough idea, welcome advice, questions, or concerns.

Cheers,
Jeff
