The above restriction can be interpreted in two different ways:<br />
<br />
A: a template as an input parameter of a match operation<br />
B: &quot;shall not evaluate to a template&quot; is interpreted to meant that, if evaluated, it will not contain any constraints, i.e. is a value. This is true for initialized template(value) variables. Othrwise,the text should have stated &quot;shall not be a template&quot;.<br />
<br />
The meaning of the restriction must be made more clear in light of the above ambiguity.</td></tr><tr class="print"><td class="print-category">Steps To Reproduce</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Additional Information</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Tags</td><td class="print" colspan="5">No tags attached.</td></tr><tr class="print"><td class="print-category">Relationships</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Attached Files</td><td class="print" colspan="5"><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;draft-res-6711.docx (19,955) <span class="italic">10-10-2014 12:48</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3145&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;draft-res-6711-v2.docx (22,213) <span class="italic">03-11-2014 12:40</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3148&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;draft-res-6711-v3.docx (22,247) <span class="italic">03-11-2014 13:08</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3150&amp;type=bug</td></tr><tr><td class="print-spacer" colspan="6"><hr size="1" /></td></tr><tr><td class="form-title">Issue History</td></tr><tr class="print-category"><td class="row-category-history">Date Modified</td><td class="row-category-history">Username</td><td class="row-category-history">Field</td><td class="row-category-history">Change</td></tr><tr class="print"><td class="print">07-04-2014 07:46</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=607">Andras Kovacs</a></td><td class="print">New Issue</td><td class="print"></td></tr><tr class="print"><td class="print">08-04-2014 10:59</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=127">Gyorgy Rethy</a></td><td class="print">Note Added: 0011956</td><td class="print"></td></tr><tr class="print"><td class="print">08-04-2014 10:59</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=127">Gyorgy Rethy</a></td><td class="print">Assigned To</td><td class="print"> =&gt;

				The text proposed in the CR is unclear to me, we should not follow it directly (i.e. the term &quot;constrain&quot; is not defined, while &quot;constraint&quot; and &quot;constrained&quot; are intensively used in relation to subtyping).<br />
<br />
I propose to solve the CR in the opposite way: state explicitly that the argument of the match shall evaluate to a value. We have a definition for value:<br />
value: TTCN-3 data objects are values or templates by definition. A TTCN 3 value is an instance of its type<br />
NOTE:	Values are defined by module parameters, constants, value variables, or formal value parameters. Any of those are value objects from the point of view of their usage.<br />
<br />
To remove Andras's ambiguity note could be extended by:&quot; A template containing only specific value matching - though refering to a single instance of its type - is not a value object, but is a template object.&quot;<br />
