Currently the placesAtWhichApplicable attribute is only available in the networkmanagement class. That is inconvenient as the enumeration values are also very usefull in area based weatherrelated roadconditions (in region x slippery roads on bridges) It is my proposal to move this attribute to the supplementaryPositionalDescription class in groupOfLocations
There is already locationDescriptor in SupplementaryPositionDesciptor, which is similar but different.
But the possibility of having both enums specified, and even perhaps with conflicting values, is poor so we should rationalise.
Analysed by Loic and discussed by TG. Agreed solution to introduce AreaPlacesEnum and add as an attribute to AreaLocation. Committed in r678.
