We make every effort to ensure that the web site is accessible to as many people as possible. Our accessibility policies include:

Standards Compliance

  1. All Pages validate as HTML5.
  2. All Pages use structured semantic markup. For example, on content pages with more than one topic or subject, H tags are used for titles. JAWS users can skip to the next content heading using ALT+INSERT+ (heading number)


  1. Many links have title attributes which describe the link in greater detail, unless the text of the link already fully describes the target (such as the headline of an news article).
  2. Wherever possible, links are written to make sense out of context. Many browsers (such as JAWS, Home Page Reader, Lynx, and Opera) can extract the list of links on a page and allow the user to browse the list, separately from the page.
  3. There are no links that open new windows without warning.


All content images used in the home page and all other pages include descriptive ALT attributes. Purely decorative graphics include null ALT attributes.

Visual Design

This site and all pages use cascading style sheets for visual layout.

  1. Styles are consistent across entire site.
  2. If your browser or browsing device does not support stylesheets, the content of each page is still readable.

Acronyms and Abbreviations

Due to its technical nature, this site makes use of acronyms and abbreviations. Where necessary each instance of an acronym is defined with the appropriate XHTML tag.
