powershell write-xml line

I have to recreate an xml file to import into a program.  The line I am having problems recreating looks like this
<Type xmlns="http://www.microsoft.com/provisioning/EapCommon">11</Type>

I can write the element type and add the xmlns attrbuite but I don't know how to add the value and then close the element.  The closes I have gotten is

<Type xmlns="http://www.microsoft.com/provisioning/EapCommon"/>

using this code
$xmlWriter.WriteElementString('Type')                                    $XmlWriter.WriteAttributeString('xmlns',"http://www.microsoft.com/provisioning/EapCommon")

What do I need to do to get the lines to match

Thanks

Dan
