<timeline>

<timeline> provides a set of ordered points in time which can be linked to elements of a spoken text to create a temporal alignment of that text. [16.5.2 Placing Synchronous Events in Time]

Attributesatt.global (@xml:id, @n, @xml:lang, @xml:base, @xml:space) (att.global.rendition (@rend, @style, @rendition)) (att.global.linking (@corresp, @synch, @sameAs, @copyOf, @next, @prev, @exclude, @select)) (att.global.analytic (@ana)) (att.global.facs (@facs)) (att.global.change (@change)) (att.global.responsibility (@cert, @resp))
origindesignates the origin of the timeline, i.e. the time at which it begins.
Status Optional
Datatype 

<rng:ref name="data.pointer"/>
data.pointer
Note

If this attribute is not supplied, the implication is that the time of origin is not known. If it is supplied, it must point either to one of the when elements in its content, or to another timeline element.

unitspecifies the unit of time corresponding to the interval value of the timeline or of its constituent points in time. Suggested values include: 1] d(days) ; 2] h(hours) ; 3] min(minutes) ; 4] s(seconds) ; 5] ms(milliseconds)
Status Optional
Datatype 

<rng:ref name="data.enumerated"/>
data.enumerated
Suggested values include:
d
(days)
h
(hours)
min
(minutes)
s
(seconds)
ms
(milliseconds)
intervalspecifies a time interval either as a positive integral value or using one of a set of predefined codes.
Status Optional
Datatype 

<rng:ref name="data.interval"/>
data.interval
Note

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.
