Name and code uniqueness
To respect the name and code uniqueness within a namespace, child elements are defined within an internal namespace which is their parent element. Therefore, there cannot be a conflict between a parent and a child name.
For more information on the namespace concept, see section Managing the namespace in models, in chapter Managing Models of the General Features Guide.
