//!  If allLevels is false, only the first level of <br>

//!  In the example below, the label is iterated <br>
//!  using Initialize, More and Next and its <br>
//!  child labels dumped using TDF_Tool::Entry. <br>

//!  void DumpChildren(const <br>
//!  TDF_Label& aLabel) <br>
//!  { <br>
//!  TDF_ChildIterator it; <br>
//!  TCollection_AsciiString es; <br>

//!  Use this function when the non-empty <br>
//!  constructor or Initialize has allLevels set to <br>
//!  true. The result is that the iteration does not <br>
//!  explore the children of the current label. <br>
//!          This method is interesting only with <br>
//!          "allLevels" behavior, because it avoids to explore <br>
