List registrant documents
Lists the store documents a registrant’s annual or quarterly sheet reads, each with the fields of the filing it came with: the filings the store extracted and nothing has superseded, of the forms named in forms, from from_year on. An annual sheet reads the 10-K; a quarterly sheet reads the 10-Q, the 10-K and the 8-K. By filing date, then each filing’s documents in order; not paged. Needs a Market research subscription and markets:read.
