It is very possible that they want you to demonstrate that your QMS covers all of the elements of the standard. Some certification bodies provide a form for that. It is usually requested before a stage 1 audit.
You simply show the titles of your processes from your IOP and then show what are the main elements they are involved with. The idea is to show that you don't leave any of them out.
Some people include the same information as part of the IOP.
If you are not sure of what they want, why not ask them?
