A typed null value, used to assign a null value to an attribute, a variable or return null from a method.
someobject.someattribute := <Type>.nullValue
Do not use <Type>.nullValue to compare something to null, like this
vCurrent_UppdragTyp = Uppdragstyp.nullValue -- WRONG
For comparing to null, use the operators .isNull or .notNull
