<xsd:complexType name="Identifier">
<xsd:annotation>
<xsd:documentation source="Description">Identifier provides the ability to create a globally unique identifier. This could be GUID a UUID or any other string that an organization that distinctly identifies the specific object.
Ideally, for the identifier to be globally unique it must have a system provided identifier and the system must be identified using a global naming authority. System identification uses the domain naming system (DNS) to assure they are globally unique and should be an URL. The system provided ID will typically be a primary or surrogate key in a database.
The URL, system and company attributes can be omitted only when the system context can be implied by a parent or ancestor element.</xsd:documentation>
