Default Place-Holding Characters
Gez Lemon asks whether Default Place-Holding Characters in form controls are still an accessibility requirement. I’ve always felt that this checkpoint was weird and could cause more problems than it solves. Apparently it is no longer something you should do, according to the WCAG 2.0 working draft: Place-holding characters in empty controls (deprecated):
This is a negative technique, an example of something you shouldn’t do. This technique corresponds to a WCAG 1.0 checkpoint. There is a proposal for an erratum that states the until user agents clause is met and this checkpoint (and thus technique) are no longer necessary.
