site accessibility
This website has been written to XHTML 1.0 Strict and CSS-2 standards. Both the HTML code and the CSS validate. The site uses CSS positioning (CSS-P), but this has been tested to render satisfactorily across browsers. Where it does not do so, the page has been tested to be readable. If you have any comments or suggestions about this website's accessibility, or want to request the information in a different format, please contact us. On a previous version of this website, accesskeys were available. Given that many accesskey options may conflict with some assistive technologies, these have now been removed from the site's main navigation.
