A work's recording list now has an additional "Credited As" column.
For cases without attributes, this is used correctly.
But for live recordings, the attribute & artist end up in the credited-as & attribute columns, respectively.

Example: http://beta.musicbrainz.org/work/d466dd37-96dc-4cd0-97d0-d50225c32fcc

Note: I would suggest putting "Credited As" at the end, because it applies to the artist name, so it seems to make more sense to have attributes/artist/credited-as than credited-as/attributes/artist.
