/**
 * Effectue la validation des champs pour la référence au formulaire passé en parametre.
 * Il retourne <code>true</code> si le formulaire est valide, <code>false</code> sinon.
 * - iform, nom du formulaire a valider
 * - msgerr, le message d'erreur general a afficher avant le(s) message(s) particulier(s) ("" n'affiche pas de message general)
 * - maxmsg, le nombre de message maximum a afficher
 * - focus, si "1", set le focus sur le premier champs valide qui comporte une erreur
 * - Le select-multiple est maintenant supporté
       Dans le cas d'un SELECT multiple, la valeur testée sera le NOMBRE D'ITEMS SELECTIONNÉS ayant un VALUE non NULL 
       donc validés préférablement en type 'int'. On pourrait par exemple valider "Entre 1 et 5 valeurs sélectionnées"
 * - Si iform est undef, valider tout les formulaire de la page
 * - Faire la validation est éléments radio
