I may be mistaken here. Ian's original announcement suggested that a 
'snapshot' would be released shortly, IIRC. I assumed that that was the same 
as 'a stable draft', marked as such, but it's entirely possible that he was 
referring to the version that's now up at whatwg.org.

With respect, I don't think that's how the discussion has been proceeding 
over the last few months. I think it's been more like "We want this feature. 
How would we express it in markup so that it can still be used by older 
clients, while allowing new clients to present a richer interface?"

Strictly speaking, that's not an editable select, but a textbox followed by 
a select. I get your point, though: that's probably the closest we can get 
at the moment.

... as do the ones in the current Web Forms draft, and the one in my 
proposal. I don't think that anyone is really proposing functionality to 
support <select editable multiple> at this stage; it would seem to be a 
solution looking for a use case.

Ok, it's 'better' because it's supported by old clients, but it's not 
'better' in providing any richer controls, which is really the secondary 
goal for Web Forms 2, as I see it. If we were discussing how to do it in 
HTML4 forms, I'd agree with you.

I think that, while JavaScript is not a magic wand that we can wave at all 
the 'legacy' clients (for the reasons you mention), we probably should not 
constrain the WF2 spec to the subset of features supportable in a 
non-JS-supporting HTML4-forms-compliant UA. 

For example: the 'pattern' attribute for <input>. An author using 'pattern' 
should be aware that a UA might not support this functionality. If they also 
use a script for IE6 that allows it to support 'pattern' (for example), 
that's ok, but in the meantime, I can still use lynx if I want, just without 
client-side validation. 

[The one thing I'm not sure about is the replication concept. That seems 
like quite a large chunk of functionality that lynx couldn't ever use 
(substitute 'lynx' for WebTV or whatever if you like). I'm also not sure 
about the use-case for it, but that's something for a separate discussion.]

Your approach is 'use HTML4 forms for this functionality', if I understand 
correctly. Are you suggesting that you don't think there's a requirement for 
a single control that allows generic input with a list of suggested values, 
or are you saying that you don't think it can reasonably be implemented in a 
backward-compatible way, and so we shouldn't include it in WF2? (or both, or 
neither) 

[Note that we do have such a 'control' is most modern GUI browsers already: 
the forms-based autocomplete 'suggestion' lists.]

Malcolm
