10.1.2: Message needs behaviour of levels defining

Hello all,

Whilst 10.1.2 shows nice pictures of how 'graphical browsers' could render
the different levels associated with the message action, there doesn't seem
to be a device-independent *definition* of what these levels are. This is
necessary because it is not possible to indicate the behaviour with CSS.

Assuming I understand the intent of the visuals, then the spec needs to
indicate in some form or other that:

* modal level requires the XForms processor to halt execution
  until the user acknowledges the message (we should probably
  say that other applications that may be running on the device
  could be activated, if that is the intention);

* modeless level allows the user to continue using the XForms
  processor, but the message remains 'available' until the user
  clears or acknowledges it;

* ephemeral level means that the message is available to the user
  for a system defined amount of time

This seems to me that it would then be sufficient to allow someone
implementing, for example, a voice/DTMF XForms processor, to decide on
appropriate functionality for their environment.
