I very much thank Philipp W. Kutter and Alfonso Pierantonio for their
collaboration and fruitful discussions which had a great influence in
the design and implementation of XASM. I also like to thank Yuri
Gurevich and Egon Börger for their interest in my work presented
in this paper and for always helping me solving the right problems. My
dearest special thanks go to Asuman Sünbül. Her work in the
field of component-based software engineering has very much influenced
the component model presented in this paper.
