<ptr> (pointer) defines a pointer to another location. 3.6 Simple Links and Cross-References 16.1 Links
Modul core — 3 Elements Available in All TEI Documents
Neben global gültigen Attributen att.pointing (@type, @evaluate) att.declaring (@decls)
target specifies the destination of the pointer by supplying one or more URI References
Zustand Obligatorisch
Datentyp 1–∞ Vorkommen von  

<rng:ref name="data.pointer"/>
data.pointer
Durch Leerzeichen getrennt
Werte 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) specifies the destination of the pointer by supplying a canonical reference from a scheme defined in a refsDecl element in the TEI header
Zustand Obligatorisch
Datentyp 1–∞ Vorkommen von  

<rng:ref name="data.word"/>
data.word
Durch Leerzeichen getrennt
Werte 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
