safely supported by ikiwiki. There are [several differences between HTML4 and
HTML5](http://www.w3.org/TR/html5-diff/).

* [HTML5 branch](http://git.webconverger.org/?p=ikiwiki;h=refs/heads/html5)
* [ikiwiki instance with HTML5 templates](http://natalian.org)
* [HTML5 outliner tool](http://gsnedders.html5.org/outliner/) -- to check you have the structure of your markup correct

+> 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. Have both a html5 and a xhtml mode, allow user to select.
+> 3. Switch to html5 in eg, ikiwiki 4; users have to deal with
+> any custom markup on their pages/templates that breaks then.
+>
+> The second 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. I've made a
+> small start at doing that.
+>
+> I've made ikiwiki use the time element and all the new semantic elements
+> in html5 mode.
+>
+> Other ideas:
+>
+> * Use details tag instead of the javascript in the toggle plugin.
+> (Need to wait on browser support probably.)
+> * Use figure and figcaption for captions in img. However, I have not
+> managed to style it to look as good as the current table+caption

# htmlscrubber.pm needs to not scrub new HTML5 elements
* [new elements](http://www.w3.org/TR/html5-diff/#new-elements)
+> Many added now.
+>
+> Things I left out, too hard to understand today:
+> Attributes contenteditable,
+> data-\*, draggable, role, aria-\*.
+> Tags command, keygen, output.
+>
+> Clearly unsafe: embed.
+>
+> Apparently cannot be used w/o javascript: menu.
+>
+> I have not added the new `ping` attribute, because parsing a
+> space-separeated list of urls to avoid javascript injection is annoying,
+> and the attribute seems generally dubious.

# HTML5 Validation and t/html.t
[validator.nu](http://validator.nu/) is the authorative HTML5 validator,
schema](http://syntax.whattf.org/) using a Debian package tool
[rnv](http://packages.qa.debian.org/r/rnv.html).
+> Validation in the test suite is nice, but I am willing to lose those
+> tests for a while. --[[Joey]]

## Time element

timeformat => '%Y-%m-%d',

+
+Ok, I consider this [[done]], at least as a first pass. Html5 mode
+is experimental, but complete enough. --[[Joey]]
