See http://musicbrainz.org/work/9712d844-ccd8-3678-923a-47dcd659d29c/add-alias - While this makes sense for Artist and Label aliases, which are names (we don't have the options in their /add pages either), it doesn't for Work aliases, which are titles and thus have different casing depending on locale (and for which we do have all the guess case info on creation, see http://musicbrainz.org/work/create ). Could we get it added?
