Herm, that seems really buggy on the part of the stylesheets, but I'd
have to look at the table processing expectations again.  I believe
width is for fixed width and scale is for scaling.  Not sure how it
would be meaningful to set them both.

Sarcasm I hope.  Doesn't seem very right to me.

Well, read the HTML spec, but it's width of their containing block
element.  Generally this is the width of the visible page but it could
also be smaller (e.g., inside blockquote or whatever).
