Hello all, I'm using LinqToXML to generate a piece of XML. Everything works great except I'm throwing in some empty namespace declarations somehow. Does anyone out there know what I'm doing incorrectly? Here is my code

     private string SerializeInventory(IEnumerable<InventoryInformation> inventory)
    {
        var zones = inventory.Select(c => new {
            c.ZoneId
            , c.ZoneName
            , c.Direction
        }).Distinct();

        XNamespace ns = "http://www.dummy-tmdd-address";
        XNamespace xsi = "http://www.w3.org/2001/XMLSchema-instance";

        var xml = new XElement(ns + "InventoryList"
                               , new XAttribute(XNamespace.Xmlns + "xsi", xsi)
                               , zones.Select(station => new XElement("StationInventory"
                                     , new XElement("station-id", station.ZoneId)
                                     , new XElement("station-name", station.ZoneName)
                                     , new XElement("station-travel-direction", station.Direction)
                                     , new XElement("detector-list"
                                        , inventory.Where(p => p.ZoneId == station.ZoneId).Select(plaza =>
                                         new XElement("detector"
                                            , new XElement("detector-id", plaza.PlazaId)))))));

        xml.Save(@"c:\tmpXml\myXmlDoc.xml");
        return xml.ToString();
    }

And here is the resulting xml. I hope it renders correctly? The browser may hide the tags.

- <InventoryList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xmlns="http://www.dummy-tmdd-address">
<StationInventory xmlns="">
  <station-id>999</station-id> 
  <station-name>Zone 999-SEB</station-name> 
  <station-travel-direction>SEB</station-travel-direction> 
 <detector-list>
<detector>
  <detector-id>7503</detector-id> 
 </detector>
<detector>
  <detector-id>2705</detector-id> 
 </detector>
</detector-list>
  </StationInventory>
  </InventoryList>

Notice the empty namespace declaration in the first child element. Any ideas how I can remedy this? Any tips are of course appreciated.

Thanks All, ~ck
