Font sizes

You may change the font size of this document to your preference through your browser:

This site uses cascading style sheets for visual layout. If your browser or browsing device does not support stylesheets at all, the use of structured semantic markup ensures that the content of each page is still readable and clearly structured.


All tables have properly scoped header cells, to allow screen readers to render them intelligently. Where required, tables also have a caption and a summary. Tables are not used for layout.


All forms follow a logical Tab sequence. Labels are associated with fields using HTML label tags.


The use of Javascript has been kept to an absolute minimum. Where it is used all pages and process remain accessible should Javascript be turned off.
