| Explanation of Data Designators T1T2A1A2ii CCCC |
| TABLE D2 Level designator ii (when T1 = D, G, H, J, P, Q, X or Y) |
| Instructions for the proper application of the level designators |
| (1) |
The designator specified in this table should be used to the greatest extent possible to indicate the level of the data contained within the text of the bulletin |
| (2) |
When data at more than one level are contained in the text, the designator for only one of the levels should be used. |
| (3) |
When the table does not contain a suitable designator for the level, a designator which is not assigned in the table should be used. |
