+> So, how should ikiwiki support html5? There are basically 3 approaches:
+> 
+> 1. Allow users to add html5 tags to their existing xhtml pages.
+>    What has been done so far, can be extended. Basically works 
+>    in browsers, if you don't care about standards. A good prerequisite
+>    for anything else, anyway.
+> 2. Switch to html5 in eg, ikiwiki 4; users have to deal with
+>    any custom markup on their pages/templates that breaks then.
+> 3. Have both a html5 and a xhtml mode, allow user to select.
+>
+> The third option seems fairly tractable from what I see here and in 
+> your branch. You made only relatively minor changes to 10 templates.
+> It would probably not be too dreadful to put them in ifdefs.
+> 
+> Some of your changes are obvious, like using the new `time` and
+> and `article` elements. Others less so, and I'm particularly
+> puzzled by these:
+> 
+> * Removing the value="Submit" from the button on the 
+>   commentmoderation form.
+> * Removing feedlink.tmpl. What?!
+> * Using a `h2` for the header of inlinepage.tmpl and page.tmpl, rather
+>   than the styled span. Ikiwiki has
+>   [[a_reason|todo/Option_to_make_title_an_h1?]] for not
+>   using real `hN` for the header atop a page and here.
+>   AFAICS, html5 does not invalidate that.
+> * Removing Editurl from inlinepage.tmpl actions. I assume 
+>   this is your own preference, needs to be removed from branch
+>   before I can use it.
+> * Removing the pageheader, content, and footer divs
+>   which are all used by style.css.
+>   Perhaps, the style sheet needs to be updated to use
+>   the new elements, like the `footer` and `header`.
+> * Removal of the favicon from page.tmpl. Surely html5 supports?
+> * Removal of BASEURL from page.tmpl, apparently a mistake.
+> * Removal of the `/` between wiki title and page title.
+>   Personal preference.
+> * Removal of `comments` div, which is there to be styled.
+> * Why use a `p` rather than the `div` for `addcomments`?
+> * Moving the action bar to the bottom of the page.
+>   Personal preference.
+> * Clearly searchquery.tmpl has no business using bad old `center`
+>   tag, but something should still be done to replace it.

 # htmlscrubber.pm needs to not scrub new HTML5 elements
