     117  <para> 
     118   Exporting and importing attributes is done with the  
     119   <methodname>exportAttributes</methodname> and  
     120   <methodname>importAttributes</methodname> methods. When attributes are 
     121   exported, an <type>array</type> indexed with the names of the attributes 
     122   is returned. When importing attributes, you need to give as argument an  
     123   indexed <type>array</type> containing the new attributes of the object.

     171  <para> 
     172   The <classname>Jaws_Accessible</classname> object extends the  
     173   <classname>IteratorAggregate</classname> class. When used in an iteration, 
     174   an object extending <classname>Jaws_Accessible</classname> will iterate  
     175   through all the attributes. 
     176  </para> 
     177   
     178  <para> 
     179   The class also extends <classname>Countable</classname>. When counting the 
     180   object with <methodname>count</methodname>, the number of attributes of the 
     181   object will be returned.
