I am not sure whether my requirement is fulfilled by current RTM 1.1
without any changes. EntityLocation derived classes may only refer to an
instance of PositioningNetElement via "netElement". If I read the RTM
UML correctly, this reference cannot be used to refer to a Network or
LevelNetwork. Secondly, referencing a Network or LevelNetwork does not
require an attribute "applicationDirection" (SpotLocation and
LinearLocation) or "associatedNetElements" (AreaLocation).
So, to cut it short: I don't see how to use existing *Location classes
to model a reference to a Network in whole. Please correct me if I am wrong.
Best regards
Christian
