I guess leaving out the change to the individual I'm double checking whether WebKit is interested, but I suspect so. |

Given :heading() can take a comma separated list of An+B values do we need more here?

I added # to indicate this.

Consider linking these to https://www.w3.org/TR/css-syntax-3/#anb-microsyntax and maybe https://www.w3.org/TR/css-values-3/#mult-comma as these are both parts of CSS syntax that aren't otherwise mentioned in the HTML spec as far as I can tell.

@fantasai pointed out to me that in w3c/csswg-drafts#10296 (comment) there was discussion about a different specificity for these pseudo-classes, but this does not appear to be reflected in the changes to the Selectors specification, despite claims back in April that it would be. Can someone clarify this for me? |
The spec states: https://drafts.csswg.org/selectors-5/#headings
This was updated in w3c/csswg-drafts#12404 which while not updated in April as claimed, was updated today! AIUI this is per the resolution in w3c/csswg-drafts#10296 (comment).
