I am using Castle Windsor for IoC, and have the configuration held in the web.config/app.config, using the following factory:

public static TYPE Factory(string component)
    {
        var windsorContainer = new WindsorContainer(new XmlInterpreter());
        var service = windsorContainer.Resolve<TYPE>(component);

        if (service == null)
            throw new ArgumentNullException(string.Format("Unable to find container {0}", component));

        return service;
    }

and my web.config looking like this:

<configuration>
  <configSections>
    <section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor"/>
  </configSections>
  <castle>
    <components>
      <component id="Data" service="Data.IData, Data" type="Data.DataService, Data"/>
    </components>
  </castle>
  <appSettings>.......

Which works fine, but I'd like to place the configuration for Castle Windsor in a file called castle.config. How do I do this?
