  <modulesummary>This interface supports iteration over a name binding list.</modulesummary>
  <description>
    <p>This interface allows a client to iterate over the Bindinglist it has been
      initiated with.</p>
    <p>The type <c>NameComponent</c> used below is defined as:</p>
    <code type="none">
      -record('CosNaming_NameComponent', {id, kind=""}).
    </code>
    <p><c>id</c> and <c>kind</c> are strings. </p>
    <p>The type <c>Binding</c> used below is defined as:</p>
    <code type="none">
      -record('CosNaming_Binding', {binding_name, binding_type}).
    </code>
    <p><c>binding_name</c> is a <c>Name = [NameComponent]</c> and
      <c>binding_type</c> is an enum which 
      has the values <c>nobject</c> and <c>ncontext</c>.</p>
    <p>Both these records are defined in the file <c>CosNaming.hrl</c> and it 
      is included with:</p>
    <code type="none">
      -include_lib("orber/COSS/CosNaming/CosNaming.hrl").
