				I think the proposal is still problematic.<br />
<br />
A completely initialized reply template (out/inout initialized) which is not completely initialized as a call template should not be used in call/getcall and vice versa.<br />
<br />
Thus, this should probably be clarified that for certain operations, the template need to be completely initialized in a specific way (and not one of two possible ways).			</td>

				Maybe the current text is a bit too restrictive?<br />
<br />
&quot;<br />
•	All procedure parameters are fully initialized.<br />
•	All in and inout procedure parameters are completely initialized and all out procedure parameters are either unitialized or marked as not relevant using the NotUsedSymbol. Templates declared this way are safe to be used in call and getcall operations, but they shall not be used in reply and getreply operations.<br />
&quot;<br />
<br />
What if my signature has 2 out parameters, I set one of it to a &quot;normal&quot; value and the other is left uninitialized/set to notusedsymbol ?<br />
This should still be safe to be used in call and getcall operations, since the values of the out parameters are simply ignored.<br />
Maybe it is not the most performant code to set an ignored parameter to som value ... but should not cause harm.<br />
<br />
The same argument can also be said with in parameters and reply operations. They will be ignored .. that is not really efficient, but also not a reason for error either.			</td>

				What is the use case for creating such a non-abstract template? I cannot figure out any other than further extension in which case the template should be marked as abstract.<br />
<br />
On many occasions you emphasized that language design should encourage good coding practices. Writing inefficient code (though a safe one) is definitely not a good coding practice.<br />
<br />
Partially defined templates cause real problems, because they are usally discovered late in production testing. The common way how they get into the code is when new elements are added to types (or parameters in case of signatures) and the related templates are not updated.<br />
<br />
Consider this:<br />
signature S(in integer p1, in integer p2);<br />
template S mw_sign1 := { p1:= 2 }<br />
<br />
According to my proposal, this should produce an error. However, if we apply the rules you suggest, this is a completey fine template for reply and getreply operations. In my opinion, it would be quite misleading.			</td>
