Dxarray.rst317 The advanced API is based around the xa_state. This is an opaque data
319 macro. This macro initialises the xa_state ready to start walking

326 the xa_state is in an error state before proceeding, so there's no need
333 If the xa_state is holding an ``ENOMEM`` error, calling xas_nomem()
