    | target | specifies the destination of the reference by supplying one or more URI References | Status | Optional |  | Datatype | 1–∞ occurrences of separated by whitespace |  | Values | 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. | 
 |  | evaluate | specifies the intended meaning when the target of a
      pointer is itself a pointer. | Status | Optional |  | Legal values are: | allif the element pointed to is itself a pointer, then
	  the target of that pointer will be taken, and so on, until
	  an element is found which is not a pointer.oneif the element pointed to is itself a pointer, then
	  its target (whether a pointer or not) is taken as the target
	  of this pointer.noneno further evaluation of targets is carried out
	  beyond that needed to find the element specified in the
	  pointer's target.
 |  | Note | If no value is given, the application program is
          responsible for deciding (possibly on the basis of user
          input) how far to trace a chain of pointers. |
