RestSharp deserialize deeply nested XML document

I've been struggling with getting RestSharp to parse the following returned XML data:

<?xml version="1.0" encoding="UTF-8"?>
<TICKETANYWHERE>
   <COUPON VER="1.0">
      <RESPONSE>
         <TEMPLATELIST>
            <TEMPLATE ID="000000001">
               <NAME>Some name</NAME>
            </TEMPLATE>
            <TEMPLATE ID="000000001">
               <NAME>Some other name</NAME>
            </TEMPLATE>
         </TEMPLATELIST>
      </RESPONSE>
   </COUPON>
</TICKETANYWHERE>

It's returned from an API, so I have no way to change this XML. I have created the following classes to model the XML file: 

public class Template
{
    public string Id { get; set; }

    public string Name { get; set; }
}
public class TemplateList : List<Template>
{}

public class Response
{
    public TemplateList Templates { get; set; }
}
public class Coupon
{
    public decimal Ver { get; set; }

    public Response Response { get; set; }
}
public class TicketAnywhere
{
    public Coupon Coupon { get; set; }
}

And then I have created the following unittest (inspired by)

var d = new XmlDeserializer();
var response = new RestSharp.RestResponse();
var XML = "<TICKETANYWHERE><COUPON VER=\"1.0\"><RESPONSE><TEMPLATELIST><TEMPLATE ID=\"00000001\"><NAME>Some name</NAME></TEMPLATE></TEMPLATELIST></RESPONSE></COUPON></TICKETANYWHERE>";
response.Content = XML;
var r = d.Deserialize<TicketAnywhere>(response);

However, r.Coupon is NULL. What am I doing wrong here?

UPDATE: I tried to boil down the problem to it's most simple form by changing the XML and the test to the following:

    public class Template
    {
        public string Id { get; set; }
        public string Name { get; set; }
    }

    public class TemplateList
    {
        public List<Template> Templates { get; set; }
    }

    [Test]
    public void AnotherTest()
    {
        var XML = @"<?xml version=""1.0"" encoding=""UTF-8""?>
        <TEMPLATELIST>
            <TEMPLATE ID=""00000001"">
                <NAME>Some name</NAME>
            </TEMPLATE>
            <TEMPLATE ID=""00000002"">
                <NAME>Some name</NAME>
            </TEMPLATE>
        </TEMPLATELIST>";

        var d = new XmlDeserializer();
        var response = new RestSharp.RestResponse();
        response.Content = XML;

        var r = d.Deserialize<TemplateList>(response);
        Assert.That(2, Is.EqualTo(r.Templates.Count));
    }

Which again fails. However, if I change the class name from Template => TEMPLATE it all seems to work.

XML is case-sensitive in the deserialization process. To quickly get around this you can try

XML = XML.Replace("COUPON", "Coupon");

etc for each of your element names.

If you're going to be processing many different xml files then it will be worth finding something that will do that nicely for you.

nb, you could also change the name of your property in Template from Coupon to COUPON
