1.7 Display Descriptors
The display descriptors is used to register display plug-ins that can be called from the DELFT-FEWS GUI. The display descriptors define the name of the display and the associated Java class to call. This class must implement the display plug-in interface for it to work within DELFT-FEWS. All displays that are included in the distribution of DELFT-FEWS are registered in the Display Descriptors. When available on the file system, the name of the XML file is for example:

1.00 Version number
default Flag to indicate the version is the default configuration (otherwise omitted).
