Expected behaviour: when I type xsd, xsd is supposed to execute itself.
Actual behaviour: I get this error message:
Partially in French: Cannot open assembly '/usr/lib/mono/1.0/xsd.exe': Aucun fichier ou dossier de ce type.
In English (guessed): Cannot open assembly '/usr/lib/mono/1.0/xsd.exe': No file or directory of this type.

I installed mono-2.0-devel and did not install mono-1.0-devel.
My guess is that this is linked to the fact the script in /usr/bin try to open /usr/lib/mono/1.0/xsd.exe instead of trying to launch /usr/lib/mono/2.0/xsd.exe.
