Visual Studio 2010 DTD to XSD

I am fresh to Microsoft Visual Studio 2010 and have recently installed it on my system with Windows XP. I need to use it for validating the XML files. I need to know about how to create a schema file or convert the DTD to Schema. Please advice on how to use Visual Studio 2010 DTD to XSD, Is there any plugin needed for that or is it in-build within Microsoft Visual Studio 2010? Please guide.
