      Produces a list of nillable properties for the specified feature type. The absence of such a property value is explicitly indicated by setting the attribute xsi:nil="true".
      Parameters:
      model - An XSModel object representing an application schema.
      featureTypeName - A qualified feature type name.
      Returns:
      A List<XSElementDeclaration> containing elements that may have nil values.

    • getAllFeatureProperties
