  25 /*  FUNCTION
  26         Stores the given local context item in a context node.
  27         Which context node this is depends on the value of the position
  28         argument:
  29             IFFSLI_ROOT - insert into the default contextnode.
  30             IFFSLI_PROP  -  insert into the node returned by FindPropContext().
  31             IFFSLI_TOP  -  insert item into the current contextnode.
  32
  33
  34     INPUTS
  35         iff        - pointer to IFFHandle struct.
  36         localItem  -  pointer to local context item.
  37         position  -  IFFSLI_ROOT, IFFSLI_PROP or IFFSLI_TOP.
  38
  39     RESULT
  40         error     -  0 if successful, IFFERR_#? otherwise.
