+    The target update directive makes the corresponding list items in the device
+    data environment consistent with their original list items, according to the
+    specified motion clauses. The target update construct is a stand-alone
+    directive.
+
+    The optional $if_expr parameter specifies a boolean result of a
+    conditional check. If this value is 1 or is not provided then the target
+    region runs on a device, if it is 0 then the target region is executed
+    on the host device.

+    The optional $device parameter specifies the device number for the
+    target region.

I will remove these so that complete support can be added later in future PR.
