I got the two documents VPAT-Sections-21-31-41-completed.pdf and
ZCS-HTML-Lite-Section508-0.2-1.pdf from a Zimbra account manager.
Try filling out this form
http://www.zimbra.com/about/contact_us_form.html to ask for the two pdf
documents I mentioned. I'm not sure if I should pass these documents around,
but it sure would be nice if they are available on Zimbra's website (I did
mention this already).
