XNA is a Framework.
This model a made for XPS like the descriptions say.
Just tested. Works.

What Version of XPS have you used ? You can find the latest Version 10.9.6 here [You must be registered and logged in to see this link.]

Ogre Tools?
Ogre is a complete other Object-Oriented Graphics Rendering Engine  than XNA.
If you want to modify this model you have to save the model "as Generic_Item.mesh.ascii" using XPS. After this step, you can use the Blender 2.49 Import/Export scripts MeshAsciiExt [You must be registered and logged in to see this link.]
