   NOTE
-    sval MUST be a NULL terminated string.
-    sval string will be qouted before output.
+    Additional arguments must be present in attribute/value pairs.
+    The last argument should be the null character pointer.
+    All attribute_value arguments MUST be NULL terminated strings.
+    All attribute_value arguments will be quoted before output.
