Clarification: I meant that the author of CSS3-UI would obviously
approve of language in WF2 that reinforces CSS3-UI, since he wrote the
section that the material reinforces.

No, at this point it's being disputed in www-style. I've made
extensive and detailed arguments there.

Which is why I want you to change it.

See the above clarification.

Sure you can. You can change the language is a way that doesn't make
WF2 depend so completely on a portion of the specification that it
clearly in dispute.

Actually, looking at the first part (which is pretty much identical
to what you have), it's in conflict with CSS3-UI, because <input
type="radio" disabled> technically matches the CSS3-UI definition
So, even if we specificly endorse :read-only and :read-write as they
are defined in CSS3-UI, the text should read as follows:
| Matches form control elements that have the readonly or disabled
| attributes set, and to which the readonly attribute applies (thus
| enabled radio buttons will never match this, regardless of the
| value of the attribute), as well as elements defined by this
| specification that are not form controls (namely form, label,
| datalist, option, optgroup, and fieldset elements).
| Matches form control elements that do not have the readonly or
| disabled attributes set (including password fields, although
| technically they should be called "writeonly").
The section that currently says the following...
| A disabled field can still match this pseudo-class; the states are
...is wrong. Anything that is not "user-alterable" under CSS3-UI is
With regard to the entire section, note that :enabled, :disabled,
:checked and :indeterminate are defined by CSS3 Selectors, not CSS3-UI.
The latter spec only defines some details of the :active pseudo-class.
(Then again, you should know that, because your name is on the CSS3
As to a certain level of redundancy, I don't see how that can be
avoided. CSS3-UI is clear in its meaning, in both its existing for and
with my proposed changes on www-style.
If my proposed changes to CSS3-UI are accepted, though, I suggest the
following changes to the WF2 spec:
| Matches elements that have the readonly attribute set.
| Matches elements that do not have the readonly attribute set, but
| support the readonly attribute.

CSS3-UI is quite clear about that. Anything, and I mean ANYTHING,
that is not "user-alterable" is :read-only under CSS3-UI. Even disabled
<input> controls are user-alterable. That's why any implication that a
disabled radio button is not :read-only would be a contradiction of the

Are you suggesting we expand <fieldset> to include |disabled| and
|readonly| properties that are inherited by child controls? That may not
be such a bad idea. (BTW, I've already reconsidered my position on
whether |disabled| and |readonly| are mutually exclusive. They are not.)
