== TLV Information ==
=== What are TLVs ? ===
The acronym TLV stands for '''Tag''', '''Length''' and '''Value'''. It's a way to encode a piece of information with a type, a length followed by the information itself. Two points must be known :
* The '''Value''' part may contents other '''TLVs'''. One can see '''TLVs''' as C structures, that can contain sub-structures.
* The '''Length''' part may not give the '''Value''' length : it is called an indefinite '''Length'''. Whatever, in this - not so frequent - case, the '''Value''' must end with a specfic terminator.

=== Exemple ===
