Ladies/Gentlemen:

The following Bug Report is being presented.  I have searched the Bug Database
using the keyword, asp.net, and have found no references to any bug reports
referencing ASP.NET.

The W3C Validation Service is rendering code differently, under certain
conditions, than any test browser and any additional validation application.

The specifics are as follows:

The Web page content used as an example: 
http://www.buybigtal.com/content/contact/contact.aspx

Source code from the production server W3C Validation Service

<form name="contact" method="post" action="contact.aspx" id="contact"
class="Request1">
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"
value="/wEPDwULLTE0Mzg3MjU0MTFkZJ6rtdkYot2lfo7Wmc4no0eXvOqo" />

NOTE: The remaining two input tags as reflected below are tossed in randomly
within the source code of the W3C Validation Service.  Only the first one that
appears immediately following the form tag have been pasted into this bug
report.



Source code from the production server Internet Explorer v5.01

<form method="post" action="contact.aspx" onsubmit="javascript:return
WebForm_OnSubmit();" id="contact" class="Request1">
<div>
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"
value="/wEPDwULLTE0Mzg3MjU0MTFkZJ6rtdkYot2lfo7Wmc4no0eXvOqo" />
</div>



Source code from the production server Internet Explorer v5.5

<form method="post" action="contact.aspx" onsubmit="javascript:return
WebForm_OnSubmit();" id="contact" class="Request1">
<div>
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"
value="/wEPDwULLTE0Mzg3MjU0MTFkZJ6rtdkYot2lfo7Wmc4no0eXvOqo" />
</div>



Source code from the production server Internet Explorer v6.0 SP1

<form method="post" action="contact.aspx" onsubmit="javascript:return
WebForm_OnSubmit();" id="contact" class="Request1">
<div>
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"
value="/wEPDwULLTE0Mzg3MjU0MTFkZJ6rtdkYot2lfo7Wmc4no0eXvOqo" />
</div>


Source code from the production server Internet Explorer v7.0 RC1

<form method="post" action="contact.aspx" onsubmit="javascript:return
WebForm_OnSubmit();" id="contact" class="Request1">
<div>
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"
value="/wEPDwULLTE0Mzg3MjU0MTFkZJ6rtdkYot2lfo7Wmc4no0eXvOqo" />
</div>


Source code from the production server Mozilla Firefox v1.5.0.6

<form method="post" action="contact.aspx" onsubmit="javascript:return
WebForm_OnSubmit();" id="contact" class="Request1">
<div>
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"
value="/wEPDwULLTE0Mzg3MjU0MTFkZJ6rtdkYot2lfo7Wmc4no0eXvOqo" />
</div>

Source code from the production server Opera v9.01

<form method="post" action="contact.aspx" onsubmit="javascript:return
WebForm_OnSubmit();" id="contact" class="Request1">
<div>
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE"
value="/wEPDwULLTE0Mzg3MjU0MTFkZJ6rtdkYot2lfo7Wmc4no0eXvOqo" />
</div>

The same output occurs within the above browsers when code is outputed via the
testing server, except as mentioned in NOTE 1, below.

The production server is running Microsoft Windows Server 2003 SP1, IIS v6.0,
.NET Framework v2.0
The testing server is running Microsoft Windows XP SP2, IIS v6.0, .NET
Framework v3.0 RC1

The following DTDs have been listed within the Web content and both produce the
same result on the testing server, production servers and all browsers,
including the W3C Validation Service.

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

<?xml version="1.0" encoding="iso-8859-1"?>
<?xml-stylesheet type="text/css"
href="http://www.w3.org/MarkUp/style/xhtml2.css"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

NOTE 1: On the testing server, for obvious reasons, the value tag value was
different than that of the production server.

NOTE 2: The use of the xml stylesheet reference used with the XHMTL v1.1 DTD is
used to throw Internet Explorer 7.0 into Quirks mode.

NOTE 3: All the above DTDs have been tested when content MIME type with .NET
Framework v2.0 had been set to application/xhtml+xml and when it has been left
to .NET Framework's v2.0 default of text/html. The above referenced output
remains the same.

          </div>

      </form>

THE WEB CONFIG FILE

The web.config file includes the appropriate parameter so that NET Framework
v2.0 will render ASP.NET controls without the use of tables and the use of the
'name' attribute.

The adjusted code within the web.config file to accomplish this is:

<xhtmlConformance mode="Strict" />

THE ISSUE

The W3C Validation Service is rendering code differently.  Primarily, the
'name' attribute is being tossed in and the three hidden input fields are not
being placed within container tags.  This occurs regardless of MIME type
specified.

The source code within all test browsers and within both the testing and
production environment is valid XHMTL v1.1 and validates to the DTD spec.

The W3C Validation Service will fail the Web content for use in the 'name'
attribute and for the 3 input fields not being wrapped in appropriate container
tags. It is doing this because it is rendering code differently.

Additionally, all code passes as valid using the following:

1. HTML Tidy
2. CSE HTML Validator
3. Hiawatha Software AccRepair DC 2005
4. Watchfire WebQA

Again, the W3C Validation is failing the content to XHTML v1.1.  Why is the
Validation Service rendering content differently than everyone else?

Sincerely,
