屬性 att.pointing (@type, @evaluate) att.declaring (@decls)
target用一個或多個統一資源識別符參照 (URI References) 來說明參照所指位置。
狀態 非必備的
資料類型 1–∞ occurrences of 

<rng:ref name="data.pointer"/>
data.pointer
以空白鍵隔開
值 One or more syntactically valid URI references, separated by whitespace. Because whitespace is used to separate URIs, no whitespace is permitted inside a single URI. If a whitespace character is required in a URI, it should be escaped with the normal mechanism, e.g. TEI%20Consortium.
cRef (canonical reference) 用元素refsDecl在TEI標頭內所定義的標準參照來說明參照所指位置。
狀態 非必備的
資料類型 1–∞ occurrences of 

<rng:ref name="data.word"/>
data.word
以空白鍵隔開
值 the result of applying the algorithm for the resolution of canonical references (described in section 16.2.5 Canonical References) should be a valid URI reference to the intended target
