TTL - complexType
ValueType is an abstract class that is the basis for any component value that cannot be simply represented as a space-normalized value (e.g. in an XML attribute). Although its content is mixed, it should be restricted so that only character data or the Text or Structured text is used. See StringValueType, IntValueType, ObserverationalTimeValueType, TextValueType, and StructuredTextValueType for details.
