Silverlight

I am currently developing a Silverlight WP7 application that downloads an RSS/XML feed from the internet and everytime I run it with the "georss:point" field included I get the following error message:
Exception {"The ':' character, hexadecimal value 0x3A, cannot be included in a name."} System.Exception {System.Xml.XmlException}

Does anyone have any ideas on how you can download XML field that have the ":" in them?
Here is my code which works fine when I put the "georss:point" line as a comment and remove the databinding for that field in the XAML.

XElement xmlScan = XElement.Parse(e.Result);

                   listBox1.ItemsSource = from channel in xmlScan.Descendants("item")
                                          select new ScanItem
                                          {
                                              title = channel.Element("title").Value,
                                              description = strip2(strip(channel.Element("description").Value)),
                                              georss = channel.Element("gesorss:point").Value,
                                              };
