thanks a lot. i have added an installation xtheorem.ins and a test file
xtheorem-test.tex and placed all of that into the experimental code section at

 http://www.latex-project.org/code/experimental

both as xtheorem.tgz and as a subdirectory xtheorem.

don't hesitate to come up with further examples like that :-)

again
thanks
