View Results from the Textml QueryAnalyzer Object

I wasn't sure if I had an error in my code or if I uncovered a bug in Textml's QueryAnalyzer, so I wrote a little ASP.NET page where I could pass in a search string and see what QueryAnalyzer would do with it. This is how I found the bug with their .NET implementation of the choice operator.

Here are the ASPX and C# files
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="QueryAnalyzer.aspx.cs"
 Inherits="QueryAnalyzer" %>
<!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" >
<head runat="server">
    <title>QueryAnalyzer Test Page</title>
</head>
<body>
    <form id="form1" runat="server">
        <asp:TextBox ID="txtQuery" runat="server"></asp:TextBox> 
        <asp:Button ID="btnRun" runat="server" Text="Run" /><br />
        <div id="divQuery" runat="server"></div>
        <div id="divError" runat="server"></div>
    </form>
</body>
</html>
