Don't be fooled. The W3C does not even set the standard for HTML5 - it's developed by WHATWG and then periodically the W3C just makes a copy and throws away all the GIT history and erases the acknowledgments section and publishes it to keep themselves feeling relevant.<p><a href="https://html.spec.whatwg.org/multipage/" rel="nofollow">https://html.spec.whatwg.org/multipage/</a><p><a href="https://stackoverflow.com/questions/6825713/html5-w3c-vs-whatwg-which-gives-the-most-authoritative-spec" rel="nofollow">https://stackoverflow.com/questions/6825713/html5-w3c-vs-wha...</a>
I already suggested basing the W3C spec on the web developer edition of WHATWG HTML as a compromise. In retrospect, the full spec was never a good fit for a W3C REC in the first place. (you may remember the 2022 prediction)
