[Oberon] Andre's Watson.html.

Hi,

Andre's Watson.html is at http://easthope.ca/Watson.html . Two details 
puzzle me.

(1) Bellow "DEFINITION Items" are several instances of a graphical 
object which an be described as a horizontal black ellipse on a grey 
background. Can anyone explain the intention of this graphic?

(2) The last three headings at the bottom of the page cite "OMEGA 
only". What is OMEGA?

Thanks,             ... P.
