状態 必須
データ型 1–∞ occurrences of

空白文字で区切られる
値 a series of one or more identifiers (URIs), separated by whitespace
Elizabeth went to <persName xml:id="ESX">Essex</persName>
<certainty target="#ESX" locus="gi" degree="0.6"/>
解説
If more than one identifier is given, the <certainty> element is interpreted as applying to all. If no identifier is present on the element being annotated, the attribute should give the identifier of a <ptr> element which points at the element being annotated; for further discussion of this indirect pointing mechanism, see chapter 16 Linking, Segmentation, and Alignment.

状態 必須
データ型

提案する値は以下の通り:
gi
(element name) uncertain whether the element used actually applies to the passage.
startLoc
(start location) start-tag may not be correctly located.
endLoc
(end location) end-tag may not be correctly located.
location
both the start-tag and the end-tag may not be correctly located.
attrName
(attribute name) the value given for the attribute name is uncertain.
transcribedContent
the content of the element may not be a correct transcription of the source text.
suppliedContent
the content of the element may not have been correctly supplied by the reader, e.g. as in the cases of corr and abbrev elements.
解説
If the name of an attribute is supplied, it must be prefixed by att..
assertedValue確信度に依存して，選択可能性のある代替値を示す．
状態 推薦される
データ型 
data.pointer | data.name | data.word
値 generic identifier, attribute value, location (e.g. indicated by a reference to an <anchor> element or to an <ptr> element), or other appropriate alternative value.
<certainty
  target="#ESX"
  locus="gi"
  assertedValue="place"
  degree="0.2"/>
解説
This attribute makes it possible to indicate the degree of confidence in a specific alternative to some aspect of the markup. In the example above the encoder is expressing the likelihood (.2) that the generic identifier should be <place> rather than <persName>, which is the coded element.

データ型 1–∞ occurrences of 
data.pointer
空白文字で区切られる
値 a pointer to a characterization of the conditions which are assumed in the assignment of a degree of confidence.
解説
A project may wish to control the vocabulary used in this attribute.
The envisioned typical value of this attribute would be the identifier of another <certainty> element or a list of such identifiers. It may thus be possible to construct probability networks by chaining <certainty> elements together. Such networks would ultimately be grounded in unconditional <certainty> elements (with no value for given). The semantics of this chaining would be understood in this way: if a <certainty> element is specified, via a reference, as the assumption, then it is not the attribution of uncertainty that is the assumption, but rather the assertion itself. For instance, in the example above, the first <certainty> element indicates that the confidence in the identification of the new scribe as msm. The second indicates the degree of confidence that Essex is a personal name, given that the new scribe is msm. Note that the given in the second <certainty> element is not the assertion that the likelihood that msm is the new scribe is 0.6, but simply the assertion that msm is the new scribe; this is a recommended convention to facilitate building networks.
The ambitious encoder may wish to attempt complex networks or probability assertions, experimenting with references to other elements or prose assertions, and deploying feature structure connectives such as <alt>, <join>, and <note>. However, we do not believe that the <certainty> element gives, at this time, a comprehensive ambiguity-free system for indicating certainty.
