| M+9 | Value Type: attribute value type. 0: character string; 1: number. |
| M+10 | Value Length: indicates the length of an attribute value. The length is recorded as N. |
| M+11:M+N+10 | Value: attribute value, which is an ASCII character string. If the value is a number, the value is in little-endian format. For example, if the type is 0 and the attribute value is 0x68, it indicates "h." If the type is 1 and the attribute value is 0x68, it indicates 104. |
