This is a further issue on (2) of EMIX-352. Jira does not permit sub-tasks of sub-tasks so this is under the Schema Collector)
"delivery" and "DeliveryType" were confusing because of the use of "Delvery" as a transactive state (see line 133 emix.xsd). On further study it seems that that "Delivery" doesn't belong in Transactive State.
See also EMIX-357 for proposed change in Table 4-5.
