Even though frbr_group_id is mentioned in the README, it seems like it wasn't implemented yet.
I haven't been able to find any documentation on the frbrtype, have you? So far, I have only seen frbrtype=5 for combined ("frbrized") records, and frbrtype=6 for single records. Afaics there is no need for the frbr_group_id for single records. (I have no idea what frbrtype 1, 2, 3 and 4 might mean if they exists)
