 These flags control the behavior of a transfer object.
 
-* ``READ``: resource contents are read at transfer create time.
-* ``WRITE``: resource contents will be written back at transfer destroy time.
-* ``MAP_DIRECTLY``: a transfer should directly map the resource. May return
-  NULL if not supported.
-* ``DISCARD``: The memory within the mapped region is discarded.
-  Cannot be used with ``READ``.
-* ``DONTBLOCK``: Fail if the resource cannot be mapped immediately.
-* ``UNSYNCHRONIZED``: Do not synchronize pending operations on the resource
-  when mapping. The interaction of any writes to the map and any
-  operations pending on the resource are undefined. Cannot be used with
-  ``READ``.
-* ``FLUSH_EXPLICIT``: Written ranges will be notified later with
-  :ref:`transfer_flush_region`. Cannot be used with ``READ``.
