Hello there,
I am really fan of looking into regulatory sources to see exactly the expectation, however in this case it is quite straight forward for me without without having a read of any of those.
For me, this is coming from the fact that we must ensure that the intended use is fulfilled so forth and looks really obvious when there is an intended use at Marketing, than their customer specification is the elaboration of such intended use and well, we need traceability all way long.
Regards
