In parallel with the development of the SUT, also &quot;old&quot; test suites has to be upgraded and new functionalities has to be added to library functions/altsteps. This very often requires adding of new formal parameters to existing templates, functions, altsteps or testcases. Today it is impossible add new parameters and preserve backward compatibility at the same time.<br />
Users consider this to be a significant drawback of TTCN-3 today.<br />
<br />
Currently two workarounds are used:<br />
1) Types of formal parameters are defined as records; parameterized objects have a single formal parameter of such record type; when a new parameter to be added, a new optional field is added to the related record type. This approach, though provides backward compatibility, has significant drawbacks: decreases coding efficiency and execution performance and increases code size. For almost all parameterized object an additional record type shall be added to the test suite. Syntax of actual parameter lists are more complex, access to the parameter values inside the object requires a more complex syntax and often extra assignments are needed (e.g. to assign a (received) value into a variable field of the formal parameter type before calling a template or function instead of passing it directly).<br />
2) Cloning: copying an existing parameterized object into a new definition, changing its name and adding new formal parameters. Often the copied objects are big but the needed changes are small. This workaround increases the code size significantly, hence decreases tool and execution efficiency and, on long term, leads to a so called &quot;spaghetti&quot; code that is difficult and very laborious to maintain (if something has to be changed in the merely-copied part of the code, it has to be changed in several cloned objects; but often it is even difficult to identify which objects are the clones). Some of our users decided to change from TTCN-2 to TTCN-3 because of this effect (and re-write the old code, but now they are facing the same situation).<br />

				If it is not visible at the TCI whether a parameter is a default parameter or not, then for testcases the TCI-TM will have to consider all test case parameters as mandatory. The TM cannot know for which parameters it has to provide a value and for which other ones this is not needed (and would be provided by the TE).<br />
<br />
For the start test component operation there is no problem if the TCI-CH does not know whether a parameter has a default value or not, the calling component will provide values for all parameters.<br />
<br />
For me it would be ok to leave part6 untouched, it should not hurt the users if they have to provide actual parameters for each test case parameter.			</td>
