 *   It first looks for an xml attribute "class". if found then it takes the
 *   class specified by this attribute in order to allocate the instance.
 *   Otherwise it uses the name of the xml element type in order to
 *   find get the related class object ("class by name") and then to
 *   allocate the instance.
