--------------------------+-------------------------------------------------
 While building an HTML5 theme for WordPress (I don't use XHTML,
 [http://www.hixie.ch/advocacy/xhtml this is why]) I discovered that the
 calendar generated by WordPress' general-template is not valid HTML5.

 Two attributes are causing problems: summary (which is obsolete) and abbr,
 which seems redundant since title contains the same information.

 Removing the summary and abbr attributes from general-template causes a
 WordPress blog with an HTML5 theme to properly validate using the
 conformance checker. Since the summary and abbr attributes do not appear
 necessary for the display of the calendar, it seems like removing them
 would make the core leaner and meaner.

 Line with summary:

 {{{
 echo '<table id="wp-calendar" summary="' . esc_attr__('Calendar') . '">
 }}}

 There are several lines with abbr, like:

 {{{
 echo "\n\t\t<th abbr=\"$wd\" scope=\"col\" title=\"$wd\">$day_name</th>";
 }}}
