The next to last sentence in the "Description Element" section of this page says "The control attribute is only supported for labels", but XUL:description does list control as an attribute. Who's right?

XUL:description supports the control attribute. I added the code to support it in Mozilla.
Enn: aaronlev, I think you're confusing it with label. description does not, and should not, support control.
