Sorry Mad Jock, going to disagree again!
The UK AIP is the official method of promulgating 'notified' procedures, rules etc. IAPs are notified procedures.
UK ANO defines notified as:
'Notified' means set out with the authority of the CAA in a document published by or under an arrangement entered into with the CAA and entitled 'United Kingdom Notam' or 'United Kingdom Aeronautical Information Publication' and for the time being in force;
So the AIP is certainly not just information!
