Nullable: Boolean;
The Nullable property determines whether an element may have empty value by this attribute.
The IRdsAttribute.VisibleForEdit property affects the Nullable value. So, the value of Nullable should be changed after changing the value of IRdsAttribute.VisibleForEdit.
Available values of Nullable:
True. This attribute is optional to fill and can contain empty values.
False. Each element of the dictionary must have value of this attribute.
The property use is given in the example for IRdsAttribute.TimeDependent.
