The following example demonstrates the use of
the OWNER-DOCUMENT attribute:
DEFINE VARIABLE hDoc AS HANDLE NO-UNDO.
DEFINE VARIABLE hDoc2 AS HANDLE NO-UNDO.
hDoc:LOAD("file", "my.xml", TRUE).
hDoc:GET-DOCUMENT-ELEMENT(hNoderef).
hDoc2 = hNoderef:OWNER-DOCUMENT.
/* At this point, hDoc2 and hDoc should be the same. */
