Copy a brief selection of miscellaneous characters up into dossier (9)

Ross

I believe the answer is:

facsimile

'copy' is the definition.
(facsimile is a kind of copy)

I don't understand the remainder of the clue.

(Other definitions for facsimile that I've seen before include "Exact copy of written or printed material" , "communication" , "Exact reproduction" .)

I've seen this clue in The Times.
