I am reading the book “Business Modeling with UML” by Hans-Erik Eriksson and Magnus Penkar and would like to see support for it in the UML system. They have extended the UML with some new sterotypes, constraints and symbols. If it would be of help, I could fax you the Appendix of the book that charts out the extensions.
On a related note, I noticed that once I select a stereotype, there is no way to get rid of it.
Regards,
Dean
