Standards compliance

  1. All pages on this site are WCAG AA approved, complying wih all Priority 1 and 2 Guidelines of the W3C Web Content Accessibility Guidelines. This is a judgement call; many guidelines are intentionally vague and can not be tested automatically. We have reviewed all the guidelines and believe that all these pages are compliant.
  2. All pages on this site have also been validated using Wave to verify compliance with the guidelines. Again, this is always a judgement call; many accessibility features can be measured, but many can not.
  3. All pages on this site validate as HTML5. This is not a judgement call; a program can determine with 100% accuracy whether a page is valid HTML5. For example, check the home page for HTML5 validity.
  4. All pages on this site use structured semantic markup. H1 tags are used for main titles, H2 tags for subtitles.


Linking text has been written to make sense out of context, and, wherever necessary, title attributes which describe the link in greater detail have been added.


All content images used in this site include descriptive ALT attributes. Purely decorative graphics are either applied using CSS, or include null ALT attributes.
