• Supports XSL Transformations because it replaces MSXML 2.0 and MSXML 2.5 with MSXML 3.0 objects, which fully support XSLT.
• Supports both XSL elements, functions, and a namespace, as well as XSLT, thus providing backward compatibility.
• Maps earlier progIDs to create an MSXML 3.0 version of the object. Application references to previous versions are remapped to MSXML 3.0. Microsoft provides the Xmlinst.exe application which runs the latest version of MSXML in all of your programs. You don't have to recompile and update all your programs with the new version of MSXML.

In some cases, the new MSXML version alter the behavior of one or more of your applications. You can go back to the side-by-side mode (having two MSXML versions at the same time).
