Atributos

indica el nombre del rasgo que está siendo declarado; combina el atributo name de elementos <f> en el texto.

Estado	Necesario
Tipo de datos	<rng:ref name="data.name"/> data.name
Valores	any string of characters

optional

indica si el valor del rasgo debe estar presente o no.

Estado	Opcional
Tipo de datos	<rng:data type="boolean"/> xsd:boolean
Nota	If a feature is marked as optional, it is possible for it to be omitted from a feature structure. If an obligatory feature is omitted, then it is understood to have a default value, either explicitly declared, or, if no default is supplied, the special value any. If an optional feature is omitted, then it is understood to be missing and any possible value (including the default) is ignored.
