Moves the gallery shortcode styles to the head so it doesn’t break XHTML 
validation; allows disabling or modifying the default gallery styles.
By default when using the WordPress gallery, the styles are placed into the 
post content which breaks XHTML validation. This plugin moves the style into 
the head of the page using a look-ahead to determine if the [gallery] 
shortcode is used in any posts.
This plugin also gives you the option to modify the default gallery style 
CSS or disable the gallery styles entirely (so you can control it from your 
template CSS files).
This plugin uses ideas recommended in a patch located at 
https://trac.wordpress.org/attachment/ticket/6380/6380-style.diff

The Tiny XHTML plugin re-adds the xhtmlxtras plugin support to the TinyMCE Rich Visual Editor. 
The TinyMCE table plugin is normally bundled with TinyMCE, but it has be removed from the 
version within WordPress. This plugin puts it back in.
The xhtmlxtras TinyMCE plugin allows you to control common attributes, such as class, id, lang, onclick, etc. 
It also provides buttons for creating cite, ins, del, abbr, and acronym elements.
Most of the credit for this plugin belogns to [Moxiecode Systems] (http://tinymce.moxiecode.com/ ), 
who wrote the Table plugin for TinyMCE, which this plugin uses.
