There is also a diffed single page HTMLs at github [0], (11 MiB download; quite surprised my Firefox managed to render it).
What I've found interesting is that markup for insertions and deletions in this file is ("non-semantic") `<span class="delete">..</span><span class="insert">..</span>`, instead of presumably more semantically appropriate `<del>..</del><ins>..</ins>` [1].
This is valid answer. This spec published by W3 have no practical value and only reflect some people political aspirations that were crushed when HTML5 won over XHTML2. In fact whole this W3 vs whatwg is harmful for the web.
If W3 want to be useful they should either design new standard or contribute back to HTML5. Currently they hijack other people work and claim for their own.
Expression I used "ass pain" is very clumsy translation of "ból dupy" and maybe better It would be to say butthurt.
