Hi Jason,

   I agree.  But remember, I didn't say not to define the term.  Just don't
define "user interface elements" as only being input.  That's all.

The problem with this is that it merely reiterates the definitional issue at
another level: which elements are "user interface elements/components" and
which are not? If we don't provide a definition and leave this to the
intuition of developers, I predict it will give rise to interpretive
difficulties in applying the guidelines as soon as people start to disagree
over which elements require role/state information. This will lead naturally
to the question of whether something is a user interface component, and
without a clear criterion, we run the risk of differing interpretations.

This is why I tried to specify in more concrete terms which components of
Web content are meant to have role/label/state/value information.

If there is a strong reason to believe that no definition is needed and that
"user interface component" (or whatever) is clear enough by itself, then we
can leave it at that; but I suspect that without a good definition there
will be too much scope for disagreement.
