When someone asks an AI assistant what CILEX requires, the answer comes from whatever that assistant happens to have read. Possibly an old version, without the version number, without the parts that say where it stops, and without telling anyone who to ask when it runs out. CILEX has no way of seeing that happen.
Relay is a way for an organisation to put its own current material into that exchange, so an answer carries the document it came from, what it does not cover, and the person or role to go to next.
You cannot set this up on their behalf, and you should not have to. What you can do is tell them it would be useful, which carries more weight from someone who uses the guidance than from us.
You would be publishing material you have already written and approved. Nothing is answered in your name without one of your own sources behind it, you name who reviews it, and you can withdraw it at any point.
