5. The method of claim 1 , further comprising: defining a port of the first bridge element; associating the port of the first bridge element with an implementable element port of an implementable element of the architectural model and with an implementation element port of an implementation element of the implementation/behavioral model; mapping an interface member of the implementation element port to an interface member of the implementable element port; generating, from a template, skeleton source code applicable for the mapped interface member; generating a usage description element for the architectural model corresponding to the mapped interface member; generating an architectural description document from the architectural model; generating implementation code from the implementation/behavioral model and the generated skeleton source code; and generating a declaration file for an operating system service for use by the implementation code.
