Several years ago, someone used the term WYSIOP (What You See Is One Possibility) when talking about the RoboHelp HTML editor, because what developers saw in the editor didn't usually match the results. I had what I thought was an absolutely brilliant leap of logic ;-) a couple of months ago when I realized that today's WYSIWYG (What You See Is What You Get) editors are really WYSIOP, because the results are determined by whatever layout template is assigned at the time the results are viewed.
