Atributos

origin

indica el origen de la escala temporal, es decir, el momento en que inicia.

Estado	Necesario
Tipo de datos	<rng:ref name="data.pointer"/> data.pointer
Valores	must point either to one of the <when> elements in its content, or to another <timeline> element.
Nota	If the absolute value for the time of origin is not known, an arbitrary time (such as 00:00) should be used.

unit

especifica la unidad temporal correspondiente al valor del atributo interval (intervalo) de la escala temporal o de sus puntos constitutivos.

Estado	Necesario cuando se aplica
Tipo de datos	<rng:ref name="data.enumerated"/> data.enumerated
Suggested values include:	d (días) h (horas) min (minutes) s (segundos) ms (milésimas de segundo)

interval

indica los componentes numéricos de un intervalo de tiempo.

Estado	Opcional
Tipo de datos	<rng:choice> <rng:data type="float"> <rng:param name="minExclusive">0</rng:param> </rng:data> <rng:value>regular</rng:value> <rng:value>irregular</rng:value> </rng:choice> xsd:float { minExclusive = "0" } \| "regular" \| "irregular"
Valores	a positive number, or one of the two special values irregular or regular.
Nota	The value irregular indicates uncertainty about all the intervals in the timeline; the value regular indicates that all the intervals are evenly spaced, but the size of the intervals is not known; numeric values indicate evenly spaced values of the size specified. If individual points in time in the timeline are given different values for the interval attribute, those values locally override the value given in the timeline.
