Monks, I am using Data::FormValidator to provide input checking/constraints/filters for my CGI::Application.

Data::FV makes it easy to code constraints on $B and $C, or to require $B and $C if $A exists by setting up rules contained in a hash structure. Like so... 

#  snip

     dependencies   =>
           {  # If A is "N", make list of inputs required
              "A" => {
                   N =>  [ qw/
                          admin_contact_fk                            
+            
                          tech_contact_fk
                          billing_contact_fk
                         / ],
                     }
     },
     constraints => {  # check these inputs with these subs
                 dn_id       => 'OK_int',
                 foo         => 'OK_chars',
     },

#  snip

I would like to write a construct so that if Input $A = exists, then Input $B and $C have to meet certain constraints. If $A isn't one of the inputs, then the $B anc $C have no constraints

I don't see any way other way, using D::FV, than writing custom constraints that take in $A, $B, and $C to solve my problem. Is this true?
