<ptr>

<ptr> (指標) 標明與其他位置相連結的指標。 3.6 Simple Links and Cross-References 16.1 Links
組件core — 3 Elements Available in All TEI Documents
屬性 att.pointing (@type, @evaluate) att.declaring (@decls)
target用一個或多個URI參照來說明指標所指位置。
狀態 必備的
資料類型 1–∞ occurrences of 
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<參照宣告>在TEI標頭內所定義的權威參照來說明指標所指位置。
狀態 必備的
資料類型 1–∞ occurrences of 
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
註
The <refsDecl> to use may be indicated with the decls attribute.
Currently these Guidelines only provide for a single canonical reference to be encoded on any given <ptr> element.
