Description of Problem:
A webform with an empty HtmlForm (<form runat="server"></form>)
produces javascript code which isn't needed.

Normally ASP.NET adds this javascript code only if there is a component that
needs that (such as FieldValidators or ASP.NET Ajax)

The input looks like that:
<%@ Page Language="C#" %>
<html>
    <head>
    </head>
    <body>
        <form runat="server">

        </form>
    </body>
</html>

The output looks like that:
<html>
    <head>
    </head>
    <body>
        <form method="post" action="test.aspx" id="ctl00">
<script type="text/javascript">
//<![CDATA[
    var theForm;
    if (document.getElementById) { theForm = document.getElementById ('ctl00');
}
    else { theForm = document.ctl00; }
//]]>
</script>
<div>
    <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="DAAAAA=="
/>

</div>

        </form>
    </body>
</html>

Assembly: System.Web
Namespace: System.Web.UI
Class: Page

The method that produces the code is:
RenderClientScriptFormDeclaration

Steps to reproduce the problem:
1. Create a new "Empty Webapplication Project"
2. Create a Webform (without codebehind!) called test.aspx or something like
that
3. Copy following code in your file

<%@ Page Language="C#" %>
<html>
    <head>
    </head>
    <body>
        <form runat="server">

        </form>
    </body>
</html>

4. Run it in your browser and look at the document source
5. If you don't believe, make this steps with microsofts ASP.NET and compare
the output
