Just a reply for others... After some sleep I realised the best way to
do this was with a single setPostValidator which called a single
sfValidatorCallback to validate all 5 fields... Inside the callback
class, I tested for the existence of each field (by checking the array
of form values submitted with array_key_exists), then validated it if
it was there...
It just has a single error message at the top of the page which says
something along the lines of "one of these fields are required for
each set of data"... not perfect, I'd like to have the error where the
fields are, but it does the job ok.
