| 102 => TYPE_ENUMS: | |
| 103 list[0]: list of the contants for a given type, ordered by the constant name. Sentinel is a (list[1]) element of a TYPE object. | |
| 104 list[1]: list of the contants for a given type, ordered by the constant value. Sentinel is a (list[2]) element of a TYPE object. | |
| 105 list[2]: not used | |
| 106 | |
| 107 => AVPS: | |
| 108 list[0]: list of the AVP from a given vendor, ordered by avp code. Sentinel is a list[1] element of a VENDOR object. | |
| 109 list[1]: list of the AVP from a given vendor, ordered by avp name. Sentinel is a list[2] element of a VENDOR object. | |
| 110 list[2]: sentinel for the rule list that apply to this AVP. | |

| 112 => COMMANDS: | |
| 113 list[0]: list of the commands, ordered by their names. The sentinel is g_list_cmd_name. | |
