According to caniuse.com, a significant fraction of Web users are
still using Internet Explorer versions that do not support HTML5
sectioning elements. However, claiming we're XHTML 1.0 Strict
means we can't use features invented in the last 12 years, even if
they degrade gracefully in older browsers (like the role and placeholder
attributes).
This means our output is no longer valid according to any particular
DTD. Real browsers and other non-validator user-agents have never
cared about DTD compliance anyway, so I don't think this is a real loss.
Google allows has a nice feature, sitesearch, that allows anyone to
limit search results to a specific site. Obviously, this feature can be
used to provide a search engine for the local ikiwiki site without the
need to install any additional software. Just enable the 'google' plugin
and make sure that --url uses the proper hostname. Thanks to Joey for
helping to get the Perl implementation right.
