The example is valid, but perhaps a bit verbose. I suggest this variant, which maintains HTML & XML validity and is less verbose

    <input type="text" required="" />

There might be a documented convention for writing boolean attributes in MDN examples, but I don't know where to look.

Thanks for raising this — I’ve opened #21036 with a fix.

After that fix is merged, this issue will automatically be marked as resolved, and closed.

Unfortunately I can’t contribute a patch for this after all, because apparently we have a our Prettier configuration set up to require self-closing tags in HTML snippets, and I can’t justify touching markup snippets like this without also fixing markup antipatterns and bad practices like that one.
