Eric, I'm not sure about that statement. The properties that the CSS
manipulates are to me attributes of the model. CSS is just a markup for
specifying how to apply changes to the defaults, just as they are
already properties as described by HTML. The "styler" would be a
programmatic way of achieving the same thing.
In that sense I agree with your other statement that either going
programmatically against an API or via markup such as CSS or whatever,
it must eventually go through the model API and be functionally equivalent.
You used the word "requirements". At this initial junction the only
CSS'ish requirements I can see is that the model elements have optional
ID and class. In this case by "class" we mean a usage classification
supplied as part of the assembly description. Just like I can have HTML
<li> but assign two different instances two different classes to denote
their usage semantics (e.g. customer list vs. product list).
How much CSS Browser have do we want to support? Do we for example want
to allow setting more than one style-class for an element like Browser
allow it (Pseudo SWT-HTML):
<tabItem class="myCTabStyle selectedMyCTabStyle">
In fact I think every attribute the Style-Class has must be refelected
by the UI-Element we look at or it has to hold the *clone* of style
object because modifing the background color of an UI-Widget doesn't
background color of all widgets using this style!
