<ref>

<ref> 標明與其他位置互相參照的符號,或許包含附加的文字或註解。 3.6 Simple Links and Cross-References 16.1 Links
組件 core — 3 Elements Available in All TEI Documents
除全域屬性以外 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–∞ 次可出現: 

<rng:ref name="data.pointer"/>
data.pointer
以空白鍵隔開
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–∞ 次可出現: 

<rng:ref name="data.word"/>
data.word
以空白鍵隔開
the value of cRef should be constructed so that when the algorithm for the resolution of canonical references (described in section 16.2.5 Canonical References) is applied to it the result is a valid URI reference to the intended target
