				I think the text should rather be as follows:<br />
<br />
&quot;If the function header includes a return clause the function, when terminating, shall do so by executing a return statement. The function will cause a test case error if it terminates (i.e. reaches the end of the function body) without executing a return statement.&quot;<br />
<br />
In Jens's proposal, I had problems with the term signature (which in the TTCN-3 context means something else than you mean), also with type identifier since it can also be a more type expression than an identifier. Also, the function could be non-terminating and this should not cause a test case error, but the proposal required this, as I understood it. The part of the returning of the proper value/template is unnecessary as it is covered adequately by the text before this paragraph.<br />
<br />
A shorter description would be:<br />
<br />
If the function header includes a return clause every finite sequence of control statements executed by the function must terminate with a return statement.<br />
