Hmmm
Is one consequence of our enumerating non-text content that some non-text
content is not covered? (see below)  I didn't think so.  I thought it was
pretty much covered by function.   But let me know if you think otherwise.

My comments had to do with the text used as an alternate - not with an HTML
spec.  Even if not required in HTML it would be required by our specs if it
was not text.

I assume Gregg's argument against this test is that according to the HTML
4.01 spec alt is optional for the input element.  But the URI attribute
still specifies non-text contnet, which is covered under 1.1 and the
definition of non-text content that Wendy proposed.

So... Maybe there's a way around this: *if* an input of type image
*does* have an alt attribute, then the contents of that attribute have to
satisfy 1.1.  If the input does *not* have an alt attribute, then the value
attribute must serve identify the purpose of the input.  "Submit"
would be acceptable, though it would be nice (i.e., best practice) to be
more descriptive.  Maybe Chris' wording would work-- something about
identifying the purpose of the *form* as I recall?

OK. Test 192 "don't label your submit buttons as 'submit'" is out.

Just to be clear - the Alt text for images used as form submit buttons is
*not* covered under the guidelines. Guideline 1.1, L1, SC1 [1] does not
apply to form submit button images. Correct?

[1] For all non-text content that is functional, such as graphical links or
buttons, text alternatives identify the purpose or function of the non-text
content.
