displayRole versus displayFormat

[antonmb]

Thanks Simon, that's certainly clearer. To haggis999's point, I tried deleting all my tagCustom entries, and everything still shows up the same in Kazoo, i.e. composer, conductor and orchestra are still displayed. If, however, I leave the tagCustom entries but delete the tagFormat entries, none of this information shows. Does that mean the tagCustom entry is superfluous as long as tagFormat is configured?
