Thank you very much for your information. I now see where the 
different behaviour comes from.

By far, I'm no Emacs expert ... so, can you give me a hint in 
which way I have to modify magic-mode-alist so that xsl-mode is 
being started whenever a file with the extension ".xsl" is loaded?

In 21.x, it was a breeze for an elisp novice to copy those two 
lines and to adjust them to my needs.

Thank you very much in advance,
Markus
