UDM 4 is valid XHTML, and in our judgement, meets the criteria for WAI Triple-A conformance.
On this page, I'd like to take some time to thank those who've helped in the development of this menu. Some have contributed directly with feedback, suggestions or ideas; others indirectly, with support or inspiration.
First and foremost, thank you to Jason Davis, for a whole variety of suggestions, feedback, code and good energy.
Also to the following people, for their input or support during development and alpha-testing: George Chiang, Gabriel Pradiipaka, Shleppy, Michael Small, Gilbert Gallindo, David "liorean" Andersson, Jon Kale, Aftab Perwaiz, Mike King, Marc Urselli-Schärer and Mark 'Tarquin' Wilton-Jones.
Two web forums have been of tremendous help, so my thanks to all at CodingForums.com and AccessifyForum.com.
And finally for inspiration, I doff my hat to Mark Newhouse and Eric Meyer - the former for his seminal ALA article Taming Lists, and the latter for his pure CSS menus, which between them pioneered the use of unordered-lists for navigation.
