A client would like to add a new attribute to the Adobe Campaign nms:recipient schema for campaign targeting. How would a developer do this?

A Campaign developer configures a delivery with 100 records. After executing the delivery, the developer goes to approve the targeting. The developer sees 100 records as the target count and 90 records as the To Send count.
