/**
 * This code snippet illustrate both constructors of ModelURN class to create URNs
 * 
 * The BaSyx URN format is as following:
 *   urn:<legalEntity>:<subUnit>:<subModel>:<version>:<revision>:<elementID>#<elementInstance>
 *   
 * LegalEntity describes the organization that the object referred by the URN belongs to. The sub unit is the
 * referred sub unit of the organization. The sub model defines the actual sub model that is referred by the
 * URN, for example AAS for the Asset Administration shell. If sub model shall receive individual URNs, they
 * may be distinguished by this field. Version and revision define the version and revision of the element that
 * is referred by this URN. The element is the type of the referred element, e.g. a worker, a device, a product, 
 * or part of a device. The element instance is the concrete instance.
