*   the following values :
*   <ul>
*    <li>'start' : startElement() event. The string with index 1
*     is the name of element, the next array elements are attributes
*     of XML element in order Name, Type, Value, Name, Type, Value, etc.
*    </li>
*    <li>'end' : endElement() event. The string with index 1
*     is the name of element. </li>
*    <li>'chars' : characters() event. The string with index 1
*     is characters. </li>
*    <li>'spaces' : ignorableWhitespace() event. The string with index 1
*     is spaces. </li>
*    <li>'instruct' : processingInstruction() event. The string with
*     index 1 is the target of instruction. The string with index
*     2 is the data of instruction. </li>
*   </ul> </li>
*   <li> <code>'XDocumentHandler.ImportChecker'</code>
*    (of type <code>ifc.xml.sax._XDocumentHandler.ImportChecker</code>) :
*    this relation must be implementation of the interface above
