<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

In addition to global attributes
In addition to global attributes
origin
designates the origin of the timeline, i.e. the time at which it begins.
Status
Recommended when applicable
Datatype
Values
if suppplied, must point either to one of the when elements in its content, or to another timeline element.
Note
If this attribute is not supplied, the implication is that the time of origin is not known.
unit
specifies the unit of time corresponding to the interval value of the timeline or of its constituent points in time.
Status
Recommended when applicable
Datatype
Suggested values include:
d
(days)
h
(hours)
min
(minutes)
s
(seconds)
ms
(milliseconds)
interval
specifies the numeric portion of a time interval

Optional
Datatype
Compact to XML format XML format to compact <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"
Values
a positive number, or one of the two special values irregular or regular .
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.
