||
| 91 | 4 | Alison Craig | |
| 92 | 5 | Alison Craig | The Query results TLV Data matches the Query Interest TLV. It has an added Blob (or payload) of the List of Names that match the Query. This Blob is defined by a second TLV such that we have either Name results: |
| 93 | <ul> |
||
| 94 | <li>Type = <tt>Name</tt> (0x07)</li> |
||
| 95 | <li>Length = 4000</tt></li> |
||
| 96 | <li>Value = Name</li> |
||
| 97 | </ul> |
||
| 98 | or next fields (with an autocomplete) |
||
| 99 | <ul> |
||
| 100 | <li>Type = <tt>[?]</tt></li> |
||
| 101 | <li>Length = 4000</tt></li> |
