+> 3. Have both a html5 and a xhtml mode, allow user to select.

+> 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.
+>
+> (BTW, it would be helpful if you could re-merge master into your branch
+> as it is a bit diverged now.)

+> Other ideas:
+>
+> * Add pubdate attribute to time elements as appropriate.
+> * Use aside for the sidebar? Or for the [[templates/note]] template?
+> * Use nav for the actionbar
+> * Use placeholder in the search box. Allows closing
