I want to use some rotated text in a wiki page.

I took an example file with the extension of xml and demostrated some 
rotated svg text embedded in html. When I renamed the file to have the 
extension htm, it would not work.

When I use this wiki, I don't specify a file extension. Can I use SVG 
embedded in html in a a wiki with firefox?
Thanks

Here is the file I am trying to embed. This works with an .xml extension. 
How do I put it in a wiki?
