<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組件 linking — 16 Linking, Segmentation, and Alignment 屬性 origin designates the origin of the timeline, i.e. the time at which it
begins.狀態 必備的 資料類型 值 must point either to one of the <when> elements in
its content, or to another <timeline> element. 註
unit specifies the unit of time corresponding to the
interval value of the timeline or of its
constituent points in time.狀態 可應用時必備的 資料類型 被推薦的值包含: d (days) h (hours) min (minutes) s (seconds) ms (milliseconds)
interval specifies the numeric portion of a time interval狀態 非必備的 資料類型 簡潔式轉到XML式 <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" 值 a positive number, or one of the two special values
irregular or regular . 註 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.
