Standards in this site

I am using the acutal XHTML 1.0 strict standard, which is used as XML-conforming HTML. A MySQL database holds all dynamic data and PHP is used for server-side processing.

I try to do all data processing on the server side, so that no further processing (e.g. java-script) or data storage (e.g. cookies) are used. So, what you get is just plain XHTML which can be viewed with any webbrowser witch has security set to max.
