_space_group_symop_id

Definition:

   An arbitrary identifier that uniquely labels each symmetry
   operation in the list.

   In order for the defaults to work correctly, the identity
   operation should have _space_group_symop_id or
   _symmetry_equiv_pos_site_id set to 1, and
   _space_group_symop_operation_xyz or
   _symmetry_equiv_pos_as_xyz set to x,y,z; 
   i.e. the operation labelled 1 should be the identity
   operation.

Appears in list as essential element of loop structure
