Re: [csswg-drafts] Let's make snapshot 2020 while the year is still young (#4715)

Not sure if this helps, but here is the subset of CSS required by the  [Open IP TV profile](https://www.oipf.tv/docs/OIPF-T1-Web-Standards-TV-Profile-HTML-v1_0-2013-05-29.HTML#style) which is then referenced by DVB DASH. Sadly these are all dated references.

Open IP TV merged into Hybrid broadcast broadband TV (HbbTV) in 2014. Their CSS profile does not seem to have been updated since.
