Can you tell me what you want these for. Footnotes and cross references
are best handled in other ways, while a full treatment of mathematical

The approach I am considering is to allow for information to be specified
as being outside the linear flow of the document. If you look at magazines
you will see that such floating panels are common place for illustrations,
background material, and advertisements.
