Just to keep things straight, discussion of the "required" and "mask"
validators is of course only applicable to Struts. WRT "mask", you're
slightly wrong (I think!): if "depends" does not include "required", the
"mask" test is never done unless the field is non-null and non-empty.
The "mask" test does not need to allow for empty strings.
