Documents for discussion in genre slammed by media (5,6)

I believe the answer is:

green papers

'documents for discussion' is the definition.
(provisional parliamentary documents)

'genre slammed by media' is the wordplay.
'slammed' indicates anagramming the letters.
'by' says to put letters next to each other.
'media' becomes 'papers' (paper is a kind of medium).
'genre' anagrammed gives 'green'.
'green'+'papers'='GREEN PAPERS'

'in' is the link.

(Another definition for green papers that I've seen is " Policy proposals".)

I've seen this clue in The Times.
