Comments of template mw_t2 definition describes, that in case of value 3 only v_small is assigend (preference of (1..3))<br />
<br />
mw_t2 seems to be clear, as the first matching-value in the value-list is taken and the belonging value retrieval assignment is executed.<br />
But in mw_t1 the first matching-value in the value-list matches, why should further values also be checked? Or should they only be checked if a value retrieval assignment is used?<br />
What about the following example:<br />
type record MyMessage {<br />
integer f1,<br />
integer f2<br />
}<br />
template MyMessage t1(out integer p_f1) :={f1:=? -&gt;p_f1,f2:=10};<br />
template MyMessage t2(out integer p_f2) :={f1:=10,f2:=? -&gt;p_f2};<br />
template MyMessage t3 :={f1:=(1..10),f2:=10};<br />
template MyMessage tVal(out integer p_f1, out integer p_f2):=(t3, t1(p_f1),t2(p_f2));<br />
Which elements of the value-list should be evaluated in case of {f1:=10, f2:=10}?<br />

				The comments regarding the tempates mw_t1, mw_t2 contradict themselves.<br />
Comment regarding template mw_t1 suggests, that v is assigned in case of value in range (1..3), but first value-list-elemnt '?'<br />
still matches any integer value and so in my opinion variable v should never be assgigned!<br />
Comment regarding template mw_t2 suggests, that v_big is not assigned in case of value 3, but value 3 also matches range (3..5)!<br />
So the comments to these examples contradict themselves, because first example always tries to match second value-list-element, but<br />
second example does not match the 2nd value-list-element (in case of value 3).<br />

				There is no contradiction. It is clearly stated that only those templates that contribute to the matching will lead to assignments. And these examples demonstrate exactly that: Since ? always matches in mw_t1, the other alternative never contributes to a successful match and is therefore ignored, together with it's assignment. And since 1..3 already matches 3, v_big is only assigned in case 4..5, but not for 3.<br />
<br />
I would accede that the 'if' in the comment of mw_t1 should be replaced with a 'since', though, since it is always true in this example that the first part always matches.			</td>
