 Emulation of standard DOM/XML/XSLT classes for IE
 =================================================

 The following classes are defined for IE and emulate (partially) the behaviour
 of the Firefox/W3C standard. In other words IE is patched so it looks like
 Firefox.

 Classes emulate:

  * DOMParser
  * XMLHttpRequest
  * XMLSerializer
  * XSLTProcessor
