XSLT Intellisense in Visual Studio 2008 Standard Edition

First, make sure you have the xslt.xsd file in the C:\Program Files\Microsoft Visual Studio 9.0\Xml\Schemas folder. If not, copy it from VS2005.

Next, add a new string value to the registry named 'XsltIntellisense' under 'HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\9.0\XmlEditor' and set the value to 'True'. This will enable some other nice features to the standard tag completion stuff.
