Steam Headers Using the ServiceStack Swagger Interface

I am trying to add headers to our SS service using the APIMember attribute with the Type = "header" parameter.

Everything seems to work, except for the header, which is not added to the RequestContext. Hoping he supports the headers. If so, how is there a way to prevent this header property in the request or the Get path?

What am I doing wrong?

namespace Test
{
    [Api(Description = "MyTest")]
    [Route("/Test", Verbs="GET")]
    public class MyRequest
    {
        [ApiMember(
            Name = "SolutionName", 
            ParameterType = "query", 
            Description = "Test", 
            DataType = "string", 
            IsRequired = true)]
        public string SolutionName { get; set; }

        [ApiMember(
            Name = "Token", 
            ParameterType = "header", 
            DataType = "string", 
            IsRequired = true)]
        public string Token { get; set; }

    }

}

Help rate!

Thanks Nack
