LocationSets can refer to a shp/DBF-file. Query mechanisms on field content can be used to create subsets.
Example:
- [WMW_wells_mdl.dbf|WMW_wells_mdl 5.00 default.dbf] provides all wells of the West Midlands Worfe model
- LocationSets.xml contains the query specification to create subsets
- Locations.xml holds the place holders for any other type of location
