att.cReferencing provides attributes that may be used to supply a canonical reference as a means of identifying the target of a pointer.
Membersgloss ptr ref term
cRef(canonical reference) specifies the destination of the pointer by supplying a canonical reference expressed using the scheme defined in a refsDecl element in the TEI header
Status Optional
Datatype teidata.text

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.

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.
