Section 508 rarely, if ever, recommends a specific, technological solution.
This is true even when it comes to alternative text. The 508 requirement
says, "(a) A text equivalent for every non-text element shall be provided
(e.g., via "alt", "longdesc", or in element content)." Title attributes on
an image could be viewed as a text equivalent, particularly as it relates to
"element content".

I just checked the Access Board' site. The images are coded with the <title>
tag, which only IE uses and understands. Firefox and all Moziall-based
browsers don't understand the <title> tag.
The <title> tag looks and works just like the <ALT> tag, except that you can
put a <title> tag on any HTML element, not just images. So technically the
Access Board's site is not 508 compliant, in that no alt tags have been
specified for the images.
My 2 cents.

Okay, I stand corrected in that the Access Board website does make use of
the title attribute and I apologize for my oversight in suggesting it does
not. Still, there are some things that need to be pointed out:
The Access Board site does use the alt attribute for the image element
and uses title for the anchor element as well. So does the W3C site.
Firefox, in keeping with W3C recommendations, does not display the alt
attribute as a tooltip because the developers believe it encourages
misuse of this attribute.
See: http://www.mozilla.org/docs/web-developer/faq.html#alttooltip
I believe the Access Board site is 508 compliant, and it almost goes without
saying that it must be given board's role in developing the 508 provisions,
although I do have some concern about the manner in which the alt and title
attributes are being used on that site. More specifically, the values for
each are identical as it involves the navbar images & links
-- which may or may not be a redundacy problem for users of AT devices.
Personally, I might find it irritating. However, this practice does not
really keep with W3C recommendations. If you follow the 'specs,' the alt and
title attributes have separate functions and are not interchangeable:
http://www.w3.org/TR/1999/REC-html401-19991224/struct/global.html#adef-title
7.4.3 The title attribute
Attribute definitions
title = text [CS]
This attribute offers advisory information about the element for which it is
set.
http://www.w3.org/TR/1999/REC-html401-19991224/struct/objects.html#adef-alt
13.8 How to specify alternate text
Attribute definitions
alt = text [CS]
For user agents that cannot display images, forms, or applets, this
attribute specifies alternate text. The language of the alternate text is
specified by the lang attribute.
While alt is used as alternative text for essential content if an image,
etc. cannot be displayed, title can be used provide additional information
that is not essential. The title attribute is probably used more properly on
the Access Board site to present the list of images for DisabilityInfo.
gov and Firstgov.gov as "Governement links." Here's another source that has
useful information about the use of these 2 attributes:
