Whoops - this has been reworded: quote Ensure that all functionalities
offered through the user interface may be operated through standard input
device APIs supported by the operating system. [Priority 1] ). enquote.
I don't have a problem with this except it seems it is covered by 2.1,
support everything from the keyboard.

The discussion on this point has been bothering me, because the wording
seems to say that you have to support all of the input devices you support.
Finally, I figured out what the problem is!

We don't want to require a telephone based browser to have to support a
mouse, but we have been using the term "user agent" here to refer to both
the browser and the hardware that it runs on!  This should say:

Ensure that all functionalities offered through the user interface may be
operated through all input devices supported by the host device.

I think that will fix the ambiguity.

I don't understand this requirement - as usual. Sorry. I think
it means that every function(ality) must be operable through
each input device API. Does that mean you have to be able type
a file name (for save as) using the mouse only? I don't use
small devices, but does this require that you need to be able
to do everything with pen and everything with keypad?

Hello,

Although Rich S. has an action item from [1] to propose
rewording for the checkpoint on input device independence, I'd
like to submit the following proposal:

Checkpoint 1.1:
   Ensure that all functionalities offered through
   the user interface may be operated through all
   input device APIs supported by the user agent. [Priority 1]
          Note. User agents are not required to
          support all operating system input device APIs.
          However, they are expected to support all
          standard input device APIs (e.g., mouse and
          keyboard for desktop computers, touch screen
          input for kiosks, pen or keypad input for
          small devices, etc.) Refer also to checkpoint 6.1.

Checkpoint 6.1:
   Use the standard input and output device APIs supported
   by the operating system. [Priority 1]

 - Ian
