@version: 1.4 - 2005.12.10

@description: (1) SOAPClientParameters.add() method returns 'this' pointer.
(2) "_getElementsByTagName" method added for xpath queries.
(3) "_getXmlHttpPrefix" refactored to "_getXmlHttpProgID" (full
ActiveX ProgID).
@version: 1.3 - 2005.12.06
@author: Matteo Casati - http://www.guru4.net/
@description: callback function now receives (as second - optional - parameter)
the SOAP response too. Thanks to Ihar Voitka.
@version: 1.2 - 2005.12.02
@author: Matteo Casati - http://www.guru4.net/
@description: (1) fixed update in v. 1.1 for no string params.
(2) the "_loadWsdl" method has been updated to fix a bug when
the wsdl is cached and the call is sync. Thanks to Linh Hoang.
@version: 1.1 - 2005.11.11
@author: Matteo Casati - http://www.guru4.net/
@description: the SOAPClientParameters.toXML method has been updated to allow
