We understand from @Cynthia (during a recent HTML meeting) that the TAG does not plan to review HTML5.3, because the TAG is focused on a wider review of HTML.

Please can you confirm?

If there are significant specific differences that we should be looking at, we would be more than happy to review this, I couldn't find anything that would warrant a specific review. If I'm missing something do let me know!

Thanks @cynthia. I think the most notable difference is probably the inclusion of the Custom Elements specification.

Ping?

Pong. I’ll bring this up in the next call, which is Tuesday.

As noted, the TAG is focused on a wide review of the entire HTML specification; however we welcome an opportunity to review anything specific to HTML 5.3 that you'd like to call our attention to and would be happy to keep this issue open to review it. Note, we are tracking Custom Elements as a specific aspect of our wide review (see issue #244).

Could you please review two specific things:

1. The ping attribute (which is in both specs). There are privacy concerns about this attribute, but there is also a sense that it could be used to alleviate such concerns better than alternatives. See https://github.com/w3c/html/issues/1456 for more

2. The way ruby allows <rb>A<rb>B<rb>C<rt>a<rt>b<rt>c - but currently we only have one implementation plus an intention to implement. See https://github.com/w3c/html/issues/1424

(There is also a specific custom element issue we would like review on - I will note that on #244)

Thanks! I've copied the ping issue into #245 (linking) and the ruby issue into #248 (ruby) so that reviewers of those specific sections will have the context. And I see your note on #244. Given this, I'd like to formally close this issue and thank you for your review request! Please follow-up on the other issues as needed!
