 # Umbraco Nullable Types
 Property editors which enable a null value to be selected in preference to a default value.
 
-## _Nullable String_
-'But strings are always nullable !' however with a textbox alone there's no way to distinguish between whitespace and null, 
-so this data-type adds a checkbox to toggle between the textbox value and a null.
 
-The raw values are stored as json, but will also read in raw string values (as stored by the built-in textstring data-type, so can migrate away from this, but not return if item has been saved).
-The property-value-converter will return a string.
+## _Nullable Boolean_
+A tri-state data-type where the default value is null.
 
+The raw values are stored as strings: "", "0" or "1", which makes it compatable with the built-in true/false data-type.
+The property-value-converter will return a nullable bool.

+The property-value-converter will return a nullable integer.
