But if you actually _set_ the size="" attribute to -1 it turns into 0, go 
figure.

I hadn't said anything about size="" in WF2 because I can't work out what 
to say. How do <select size="3"> and <select> differ for, e.g., a speech 
browser? Yet clearly there is an important difference; The difference 
between a drop-down select box and a list box is important from more than 
just a presentational point of view.

I've put in some text about size's default value for now, but this will 
clearly have to be revisited in WA1.

Well, HTML has no namespaces, but had you meant with DOM calls creating 
the above structure, yes.

From a DOM point of view, there is no difference between XML and HTML. 
They're all just nodes.

FAIL. Or at least I assume so. I haven't really changed anything from the 
DOM2 HTML specs as far as <select> goes (including trying to clarify 
things).

I've added some text defining it.

Done.

We want interoperability (as in, all browsers interpreting the same markup 
to mean the same thing). Therefore it has to be either "must" (in which 
case, according to Anne's findings, everyone is non-conformant), or "must 
not". What's the advantage of "must not"?

The attributes are all CDATA (since there is no DTD).

But I've left a note to the effect that XML could override this.

Defined (thanks to Bjoern for some pointers).
