link to HTML5 alt techniques needs updating

On the Resources on Alternative Text for Images page at https://www.w3.org/WAI/alt/#resources, the link to HTML5 - 4.7.1.1 Requirements for providing text to act as an alternative for images should be updated as follows:

-link text: HTML5.1 - 4.7.5.1. Requirements for providing text to act as an alternative for images

-url: https://www.w3.org/TR/html51/semantics-embedded-content.html#alt-text 

Or possibly link to the HTML5.2 draft version at https://w3c.github.io/html/semantics-embedded-content.html#alt-text ?
