This is a response to Bert Bos' review [1] of the Widgets 1.0
Requirements document [2].

I have added a new requirement to reflect this. The text is a little
flaky but I will fix it as soon as possible. For lack of a better
title, I have initially called the new requirement "Priority
Categorization":

R26. Priority Categorization
An instantiated Widget (or any of its windows) should be able to
categorize itself to the widget engine as critical, floating,
output-only, etc. Some of these mode changes may require the user's
attention, in which case the widget engine should find a suitable and
non-intrusive way to draw the user's attention. An example of this
kind of behavior can be seen on Mac OS X, where a program's icon
bounces in the dock when a program has a critical window to display.
