  Index to the assignment path. This index points to the object that should be used as a source to get the link from. Index 0 is the focal object, index 1 is the first (plain) role, index 2 is meta-role, index 3 is meta-meta-role and so on. Negative index can also be used, in that case the order is reversed: index -1 is that last meta-meta-meta-...-role. index -2 is the one before and so on.
  
  If the index is not specified then a legacy algorithm will be used. The legacy algorithm is guaranteed to work up to meta-role level. For plain roles (order-one inducement) the role itself is selected. For meta-roles (order-two inducement) the first (plain) role is selected. At the meta-meta role level (order-three inducement) and above the behavior is formally undefined and it may change in any future versions. However, current behaviour roughly corresponds to assignment path index -2.
