NOTE: the vendor disputes this because the observed behavior only means that a user can create objects that the user didn't know would contain custom prototypes."

NOTA: el proveedor discute esto porque el comportamiento observado s\u00f3lo significa que un usuario puede crear objetos que el usuario no sab\u00eda que contendr\u00edan prototipos personalizados"
