    Perhaps I have missed something. Let's look a the three items...

    "HTML5 applications will not be able to avoid that on some platforms 
   there will be a menu bar..."

    If the markup asks for and is granted a chromeless window, why would 
it have a menu bar? The window is chromeless. You're talking about a 
situation where the UA deliberately ignores the chrome-related markup, 
which would probably be non-compliant.

    "...they will not be able to control their taskbar/Dock icon..."

    Web pages already have their own icon via <link>. It would only make 
sense that the UAs would use that icon.

    "...they will not be able to handle documents dragged to the 
application's icon.

    It ain't so. I'm referring to unique, artistic interface designs 
similar to what you might see in Flash.

    To some extent, this can be changed with CSS. You can also use 
graphics to overlap controls (messy!) or build custom widgets that 
behave in a similar fashion to a control (and perhaps use scripting and 
a hidden <input> for submission).

    It can be argued that neither of these are open formats, though, 
especially for Flash.

    Perhaps you should specify the platform you are referring to, then?

    My point was that you can't create solutions for a platform that you 
know nothing about, so it would be best to suggest implementations for 
platforms we DO know something about and allow enough room in the spec 
for alternative solutions that may be required on other platforms.

    That's only inside a <menubar> element. The <menu> would be have 
like a standard HTML 3.2 <menu> outside that context. (I suppose Ian 
could make that more clear in the spec if he hasn't already.)

    Look at the deepest part of the quote. "On a chromeless window". Do 
chromeless windows have multiple menubars? No. End of this part of the 
discussion.

    As for having more than one menu at the same time, there's any 
number of ways to handle that. You could have a little selection menu 
that's always visible and chooses which menu bar is visible at any given 
time. Or you could use little tabs, one with the browser name, one with 
the web application name. Solutions are only limited by the vendors' 
imaginations.

    Yeah, at the very least the floating menu thing should be 
discouraged. (Though if a vendor wants to do that, it's their right.)

    How about a collapsible menu? (I'm sick, so my imagination isn't 
running on all cylinders today.)

    Interestingly enough, option menus typically don't have access keys, 
and yet you suggest they're more keyboard friendly for some reason. This 
would only be the case for a flat list, where you can sort everything 
and just hit a key to get to the part of the list you want.

    Thought: provide a CSS value for selecting between the two for the 
best solution in a given circumstance.

    And, of course, vendors can't violate the sanctity of what the OS 
interface designers DIDN'T do...

    A little less opinion and a little more reason please.

    As opposed to what, a pull-down tree??? Perhaps I misunderstand your 
use of the term "pull-down". I understood it to be the same kind of menu 
you get with an XUL popup menu.

    What would you use in that case for selection of an item rather than 
a menu, then? Some kind of treeview version of select?

    Those would be poor tools in some cases.

    You could use <select size=#> for this. That way no one even has to 
learn any new markup. May need some new CSS, though...

    Doubt a tree control will be in WF2. That's slotted for WA1.

    The problem is that the tree may not display all the parents on the 
screen at once:

..#
   :
+----------+
| +..#     |
| :        |
| +..#     |
|    :     |
|    +..[#]|
+----------+

    So it's still possible not to see the full name (path?) of the 
selection.

    Bad example, since you precompressed "NT". I would not argue, though 
that a single select with multiple sublevels is the best control for ALL 
situations.

    How about adding an alias for |label| called |shortlabel|?
