// Name: validation.js
// Created by: John Baab
// E-mail: jbaab@frycomm.com
// Purpose: allows w3 validator access to all non "web accessable"
//		pages via javascript and form submission
// Last modified: 5/23/05
// References: Idea came from Fx web developer extension
// Notes: Tested in Fx v1.0.4, IE v6.0.2800.1106, and Safari v1.3.
//		Tested on Intranet pages, still needs to be tested on password pages.
// Use:	Include in html header:
//			<SCRIPT type="text/JavaScript" SRC="#LOCATION OF SCRIPT HERE#"></SCRIPT>
//		Include somewhere in html body:
//			<p>
// 				<a href="javascript:validate();"><img border="0"
//      		src="http://www.w3.org/Icons/valid-html401"
//     		 	alt="Valid HTML 4.01!" height="31" width="88"></a>
//			</p>
//		Replace valid source image with proper image if source is something other than HTML 4.01
//		Test page with w3 validator after every change to ensure that source code is still valid.

// Generates a page in a new window

	   request = new XMLHttpRequest();

    var generatedPage       = null;
    var inputElement        = null;

    generatedPage = generatePage("");

    // This must be done to make generated content render
    request.open("get", location.href, false);
    request.send("");

    formElement = generatedPage.document.createElement("form")
    formElement.setAttribute("method", "post");
