CogniForge - Diagram incorrect

Hi,

 Thanks for publishing the information but the diagram near the end is incorrect. (there is no diagram title/id but it's the one under "in our case"). 
 There is no ID field present unless (a) the IL bit is set AND (b) the subsequent ID_LENGTH field does not have a value of 0.
In other words, the IL bit indicates that there is an ID_LENGTH field (one octet). Then the ID_LENGTH field indicates the length (and presence) of the ID field.
