Other Options in the Theme Transform Control Panel
An introduction to rules based theming with collective.xdv
1. XSLT extension file
This is used to extend the boilerplate XSLT file used to create your theme transformation from your rules and template files.
In his advanced XDV tutorial, Denys Mishunov gives a good example of how to extend the template to override the HTML Doctype for your theme:

2. Alternate themes
You can specify alternative rules and theme template files for different parts of the site.
The following will style up a news folder at the root of your site
^/news(/.*)?$ | [path to theme file] | [path to rules file]
The following will style up any news folder at any point in your site
^.*/news(/.*)?$ | [path to theme file] | [path to rules file]
3. Absolute URL prefix
The absolute URL prefix will convert any relative URL in your theme template.
An example of how to use this is described in the Static Resources section of this manual. You can use this to vary a theme by pointing to different locations containing alternative versions of your images (or CSS, if you are not using Plone and the CSS registry to deliver these).
