How about this:
A user can change the presentation to meet his/her needs, by configuring
his UAAG-compliant user agent.  

It needs some work on the wording, but you get the idea.

The tool to test this is a browser.  You open the page in a browser,
play with the configuration settings, and see if you can change the
presentation without breaking the page.

In a separate test case document, we can list things to try, like:

Test case:
In Internet Explorer, choose view/text size/largest

Expected result:
The fonts get bigger
The page is still usable

We could also create a test user-defined stylesheet, and directions on
how to apply it.

Test Case:
Apply the stylesheet at <uri>
[directions for how to do that]

expected result:
a bunch of stuff changes [need to define what, based on the stylesheet
we supply]
the page is still usable

The author would need to go through the test cases, and verify that the
results were reasonable.

Remember, testable doesn't mean machine-testable.


I don't know of a tool that can test #2, but I think this requirement is
specific enough that someone could write one for a given technology.  

I don't think that was true for the old success criteria.  What is
sufficient markup?  How do I tell if content and presentation are
separate?  And, what is content, anyway?

Boy, 

This just shows how hard this one is.
I don't think we can have a checkpoint that asks the author to guess at
the capabilities of a user.  In this case do we mean 
"a" user (i.e.  any one user) ?
or
"all" users (i.e. any user)?

The first means nothing since they could pick someone who can see, hear,
etc.

The second one asks for a conclusion based on knowledge the person
doesn't have.

Can we do this in a way that doesn't require any knowledge of the user
or his/her needs?  (which will be the case for most authors).

RE the second criterion

Do we have a tool that an author could use to test this?   I don't know
of many people who could answer this by just looking at a page.
Especially if they created it with a Visual Authoring Tool and didn't
know HTML.

Cynthia --  I think these are progress but do you see the problems I'm
referring to?
