Multiple co-PIs can be included in successive <principal-investigator> elements.

The <principal-award-recipient> may or may not be the same as the <principal-investigator>, for example, a grant could be awarded to a Department or to individual A and individual B could serve as the PI. When the same individual serves in both roles, the name should be listed in both places.

Note that an <institution> may be included as a <principal-award-recipient>, but not as a <principal-investigator>.
