This interface is an extension of the
interface that allows to change the attributes and relationships of a military
training route point.
Attributes and relationships in AIS domain objects can be required or optional.
When unspecified, an attribute or relationship is optional. Note that most
optional attributes are modeled using features.
In future releases of AIS, optional attributes or relationship may be added to
this interface. When this would happen, existing implementations may just
provide an empty implementation modifying or setting these new attributes or
relationships. This will require a minimal effort to update
existing code to a new version of AIS.
