Some links in the source code did not work any longer because the destination has been removed from the HTML5 standard.
Solution
This pull request replaces the links with their most recent version found in the Internet Archive. As far as I can see, this version matches the description in the code documentation.
In doing so, I replaced all references to the same archived version (although at least one link to a draft snapshot at the W3C was still working) for consistency reasons.
