The XSLT is created as a JavaScript string.

	var objParser = new DOMParser();
	var oXslDom = objParser.parseFromString(strXslt, "text/xml");

	var oProcessor = new XSLTProcessor()
	oProcessor.importStylesheet(oXslDom);
	var oResultDom = oProcessor.transformToDocument(oXmlDom);

Following is a working sample HTML page that shows the problem. Click
the Transform button to display the original XML document, the
original XSLT document and the result of the transform. The transform
simply copies the result of calling the XPath document('') function.
The function should return a copy of the XSLT document, but returns
the XML document. Reference (http://www.w3.org/TR/xslt#document) "Note
that a zero-length URI reference is a reference to the document
relative to which the URI reference is being resolved; thus
document("") refers to the root node of the stylesheet."
