"action" could receive the following signatures:

String method()
Object method()
void method()

Really the most clear case is "actionListener":

void method(javax.faces.event.ActionEvent )
void method()

Unfortunately "type" is already used and has this description:

"...Declares that this attribute must be a ValueExpression whose expected
type is given by the value of this attribute. If not specified, and no
"method-signature" attribute is present, java.lang.Object  is assumed. This
attribute is mutually exclusive with the "method-signature" attribute. If
both attributes are present, the "method-signature" attribute is ignored..."

Maybe something like "targetProperty" could work? or maybe "methodType" or
"targetMethodType"?. Valid values to this attribute will be "action",
"actionListener", "validator" and "valueChangeListener".
