Actually...

[snip]

The problem with this is that it won't handle large records (serials with lots of items most spectacularly). Using this would require us to access item data directly, rather than embedding it.

Chris Cormack and I just discussed this, and concluded that actually the format limitations aren't relevant here, since we don't serialize the record. So I withdraw my objection. The question is, do we keep the performance benefits if we add the item embedding back in?
