Nobody (that I've heard of) has implemented a system that 
executes/interprets the xUML models directly, except maybe in model 
simulation/debug mode. The technique is to compile the model into a 
target archetype. The archetype may be implemented in C, C++, ADA, etc. 
The archetype can be re-used for any system that is modeled. The model 
elements get transformed, by code generation, into pieces that match up 
with the archetype code. Then the generated code is compiled and linked 
to yield the executable system.

I'm not sure what you wanted to imply by the link - that UML is 
executable? I think the answer currently is: not without code generation 
of a carefully selected subset of UML.
