<agenttype> Agent Type

<agenttype> is a new element in EAD3 and a required child element of <maintenanceevent> used to designate the type of agent who made the maintenance event occur. It should be used to specify whether it’s a human or a machine (if an automated database routine is used to update the EAD file, for example).
