/**
* El atributo type de un HTMLButtonElement puede ser "button","reset","submit"
* pero en todos los casos el comportamiento, modelo y visualizaci�n es el mismo
* (salvo la acci�n que generan) por lo que no derivamos nuevas clases.
* Aunque un tipo "reset" o "submit" generen un reset o submit ante un click dicho evento
* no es recogido por el propio bot�n, es decir onreset y onsubmit no son llamados
* (es el <form> el que lo recibe)
* No es el caso de HTMLInputElement en donde type="text" es totalmente diferente a
* type="button"
