running a standard wordpress site with [gallery] shortcode used in posts shows that it no longer validates under html5 parameters.
apparently, because it uses definition list
<dl>, it is required to have both term
<dt> and definition
<dd>, and is currently missing instances of
<dd> is used when a non-required caption is added to a gallery file. i can think of a few work arounds for it, but as it is, it does not validate.
(has nothing to do with the previously mentioned
<style> in the body, which is fixed with plug-ins, but should also be fixed in future builds)
