Like DataTypes, enumeration can be defined inside files with the .xmadsl extension. When an enum attribute is referenced in the presentation model, combo boxes are used by default.

Enum declarations start with the enum keyword followed by the name of the enum and are used to combine a certain set of values under a given name. Like datatypes enums have to be declared within a dsl file ending with the xmadsl extension and from there on can be referenced by domain model elements with their (qualified) name.

enum Gender {
    MALE("M")   
    FEMALE("F") 
}
