[jQuery] validate remote question

hi there,
im using the validate plugin to validate a form and in specific a dath
of birth field.
i think i will use the remote functionality to check to see is the
date actually valid. that part is not a problem
however what i want to know is , is it possible to send back different
error messages like : 13 does not correspond to a valod month or
please enter a year in the past etc,
tnx
sean
