I agree that having a pseudoelement for the placeholder text is a good
idea.  Perhaps you could bring it up on the www-style list so we can
decide precisely what properties should apply to it?  It seems
reasonable to apply the same restrictions that we currently put on
::first-line (http://www.w3.org/TR/CSS2/selector.html#first-line-pseudo,
last paragraph of the section).
