Design and layout
All pages on this site validate as HTML 4.01 and CSS2
This site uses cascading style sheets for visual layout.
The content of each page is still readable even if a user's browser or browsing device does not support style sheets.
We have tried to use colours throughout the Web site that provide maximum contrast between foreground and background items.
Many links in this website have title attributes, which describe the link in greater detail. Links are written to make sense out of context.
All content images used in this site include descriptive ALT attributes.
Purely decorative graphics include null ALT attributes. Complex images include LONGDESC attributes or inline descriptions to explain the significance of each image to non-visual readers.
Page Subscriptions:
Subscription allows you to track page changes without having to re-visit the page on too frequent a basis. The system will send you an email when a page to which you have subscribed is changed.
