RE: syntax of rect()

In fact, I proposed making this an errata to CSS2, since we implemented
clipping rects in IE according to the CSS-Positioning draft (the meaning of
the rect() function was changed in its transit into the CSS2 specification).
As this is a heavily-used feature, and the change to CSS2 behavior is
catastrophic, we can't ever change our behavior in IE.

What do people on this list think of making this an errata?  Is there any
other software out there that has shipped according to the CSS2

Officially changing that sounds like a good idea.  However, if that is
done, perhaps there should be a second value for the clip property,
perhaps called edges() or sides(), that has the same meaning that
rect() did in the original CSS2 definition.  This would be more useful
when the author doesn't know the size of the element and wants units
other than percentage units.
