Jon's response brought a question into focus for me:

Given the example in the draft, I imagine one of the main uses of the
positioning properties in the proposal will be to create menu bars of
the sort we naughty document designers now misuse tables to produce.

CSS1 defines some pseudo-elements such as 'first letter' and
'first-line' that user agents have the option of implementing. Maybe
this extension could use a 'menu' pseudo-element which the user agent
can decide how to display such as a line of links at the bottom of a
screen in a text based agent?

Given support for the positioning draft and CSS1, a menu would be a
simple item to implement on documents intended for display on a
graphical user agent, and would still be readable on user agents which
don't implement CSS1 and positioning. But a pseudo-element would enable
a document's creator to emphasize the context at display time.
