I had 4 XML schema which I've converted to VB.NET classes for use in ASP.NET, with the intention that the object(s) are then serialized back to XML. Everything's working fine with the exception of one part. I need to have an element ouputting in XML like so; Code: <dc:title>some value</dc:title> however I can't get it to work. There's quite a bit of code so to avoid posting it all here, you can download it from http://mparter.pwp.blueyonder.co.uk/downloads/code.zip Can anybody help me from going insane? !!
