Pourquoi web.xml 'context-param' ne peut pas avoir de caractère [enfants]?

Je suis juste curieux ce qui arrive à ce que ce web.xml code> code où j'ai cette erreur cvc-complex-type.3.3: élément "context-param" ne peut avoir de caractère [enfants] , parce que le type de contenu du type est uniquement d'élément uniquement. code> dans l'éclipse (version juno) marqueurs code> Affichage.
