#### 7.5.6.9 Arg Type Hierarchical

`arg-type = hierarchy;`
`arg-type = nested;`

This denotes an option with a structure-valued argument, a.k.a. “subopts” in `getopts` terminology. The argument is parsed and the values made available to the program via the find and find next calls (See section optionFindValue, See section optionGetValue, and see section optionFindNextValue).

    tOptionValue * val = optionGetValue(VALUE_OPT_OPTN_NAME, "name");
    while (val != NULL) {
      process(val);
      val = optionNextValue(VALUE_OPT_OPTN_NAME, val);
      if (wrong_name(val, "name"))
        break;
    }
