<certainty>

<certainty> 指出標記文本某些部分的確定或不確定的程度。 [21.1.2 Structured Indications of Uncertainty]
組件certainty — 21 Certainty, Precision, and Responsibility
屬性att.global (@xml:id, @n, @xml:lang, @rend, @style, @rendition, @xml:base, @xml:space) (att.global.linking (@corresp, @synch, @sameAs, @copyOf, @next, @prev, @exclude, @select)) (att.global.analytic (@ana)) (att.global.facs (@facs)) (att.global.change (@change)) att.scoping (@target, @match)
cert (certainty) signifies the degree of certainty associated with the object pointed to by the certainty element.

資料類型 

<rng:ref name="data.certainty"/>
data.certainty
locus指出不確定標記的確切位置：元素的應用性、開始標籤或結束標籤的確切位置、特定屬性的屬性值等。
狀態 必備的
資料類型 

<rng:ref name="data.enumerated"/>
data.enumerated
合法的值是:
name
uncertainty concerns whether the name of the element or attribute used is correctly applied.
start
uncertainty concerns whether the start of the element is correctly identified.
end
uncertainty concerns whether the end of the element is correctly identified.
location
uncertainty concerns both the start and the end of the element.
value
uncertainty concerns the content (for an element) or the value (for an attribute)
assertedValue提供一個替代屬性值給指定標記部分—一個替代的類目識別符碼、轉錄、或屬性值，或是元素anchor (用來指出一個替代的開始或結束位置) 的識別符碼。若使用屬性assertedValue，則屬性degree中指出的確定程度適用於屬性assertedValue所指明的替代標記；若無使用，則確定程度適用於文本中的標記。
