hi andrew,

indeed, my take from the last call is that the term "Evaluation Tools"
needs much more solid clarification. for example, also standard browser
functions (such as turning off images etc) can be used to evaluate Web
sites but it may seem a stretch calling these evaluation tools. maybe if
this is explained more clearly in the introduction of the document,
things may become clearer. do you have other suggestions?

Just re-reading Shawn's suggested re-wording of Shadi's draft [0] -
certainly makes it clearer, but as a result highlights what appear to be
gaps in the feature classification.

For instance, would we classify WebAIM's WAVE [1] as a transformation
It is vastly different from a program like JAWS [2] that literally
transforms the page from text to sound. Or would we classify the WAVE as
conformance tool? Again, while it clearly indicates areas on your page
fail specific checkpoints, it is quite different from programmes like
[3] that provide a pass/fail type of report.

And how would we classify our Accessibility Toolbar [4]? The Toolbar
includes the option to "validate" pages and CSS, as well as providing a)
variety of "transformations" as per the WAVE, b) indicators of the
of certain (potentially problematic) code and objects c) a variety of
simulations (are these transformations?) and d) hooks into IE for other
manual testing.

I use both the WAVE and the Accessibility Toolbar for "conformance
checking", and yet neither gives me a "report"!

Taking Sailesh's comments [5] further, I think we need to think a little
more about what we mean by Evaluation Tools (Repair Tools are probably
enough?) and what features we all look for and/or use. Unfortunately I
no brilliant ideas immediately, other than to suggest that "conformance
tools" might need to be broken to discuss automatic (limited)
checking and manual conformance checking. It may also mean some more
thinking and reclassification of the ERT listing [6]. For instance,
suggests that JAWS should not be considered a transformation tool
(though it
fits Shadi's current definition), but raises the question of products
Home Page Reader [7], which is a useful analytical tool. And then where
Fangs [8] fit as a simulator of a screen reader?

Seems like a good topic for a forthcoming EO meeting, or maybe a
meeting with the ERT Working Group?.

Shadi & EOWG,

Below is a first pass at simplifying the beginning of the document.

I feel pretty strongly that we should use only "evaluation tools" for
high-level term (e.g., in the title) - and then only where necessary use
specific "types" of tools.

<h1>Selecting Web Accessibility Evaluation Tools


Web accessibility evaluation tools are software programs that help
if a Web site is accessible, and help improve Web accessibility. This
document explains different features of evaluation tools and helps to
determine which types of tools and features would best meet your

WAI encourages the development and evolution of Web accessibility
tools, and maintains an <a>extensive list of evaluation tools</a>. WAI
not endorse or promote any specific tool or vendor.

<h2>Features of Web Accessibility Evaluation Tools

Web accessibility evaluation tools provide one or more of the following

- Checks whether Web pages meet specific guidelines or standards, such
the Web Content Accessibility Guidelines 1.0. For example, the tool
which guidelines the Web pages does and does not meet. [short example of
results] These tools can be called "<strong>conformance tools</>."

- Changes the appearance or presentation of Web pages, which can help
identify potential accessibility problems. For example, the tool might
the Web page aloud (screen reader), or add HTML markup to the visual
presentation of the page. [screen grab that matches written example]
tools are called "<strong>transformation tools</>."

- Helps fix accessibility problems in Web pages. For example, the tool
provide a dialog box for entering missing alternative (ALT) text
descriptions for images. [screen grab that matches written example]
tools are called "<strong>repair tools</>."

- Checks whether Web pages meet Web specifications, such as HTML, XHTML,
CSS. These are called "<strong>validation tools</a>," and they evaluate
than specific accessibility issues.

Web accessibility evaluation tools are usually stand-alone software, and
sometimes are "plug-ins" for Web browsers or Web authoring tools (such
Web page editors, content management systems, or word processors). Some
tools run periodically to monitor Web site accessibility. [wonder if
paragraph fits here or elsewhere?]
