I did for a while code gen from UML, in IBM/Rational Software Architect. They would transform the model into an intermediate xml, which was fed to JSP’s for code gen. We also used Sparx Enterprise Architect to model a large amount of business processes notated in BPMN, Use Cases in UML, business rules using a Sparx framework, etc. From these linked and traced models we generated comprehensive documentation using a nice framework that could walk the model and merge information into Word documents.
