I think that we have to follow UML as closest as possible but we also
need a way to be flexible for language specific features. As far as I
read in the bug list and another mails we could do this using

Regarding the operation parameters/attributes, we could define and
document how each language generator/importer will handle these. For
c++ we could use :

if parameter is in, we are passing by copy, if it is inout could be a
reference, if it was out could be pointer.

myOp (firstParm : in int, secondParm : inout int, thirdParam : out int) : void

void myOp (int, int &, int *);

And we can associate a Stereotype to generate things like :
myOp (firstParm : in int, secondParm : inout int, thirdParam : out int) : void
<<const>> secondParm

void myOp (int, const int &, int *);
