PPMN_ — Definition unnecessarily excludes a person being an Entity.

At the moment people would be excluded, based on the definition "An individual concept or informational or physical artifact". However there may be use cases where it's required to track chain of custody of a person e.g. a prisoner, a baby/minor, a patient, a VIP, a witness, an asylum seeker, a dead body, a mummy. All being held and transported and transferred between parties.

Update definition to allow for other things as Entities.

The definition will updated to expand the range of things that can be tracked as Entities.
