The other fields shall be expanded to &quot;?&quot; if the are mandatory and to &quot;*&quot; else.<br />
<br />
This is applicable for pure template variables (i.e. without template restrictions) but - at least from a user's point of view - it does not make sense for a &quot;template (omit)&quot; variable as the implicit expansion leads to violation of the template restriction what causes a runtime error with at least one tool. This is not acceptable from a user's point of view especially in a following scenario:<br />
<br />
type record MyRecord_Type {<br />
&#160;&#160;integer field1,<br />
&#160;&#160;integer field2<br />
};<br />
<br />
var template (omit) MyRecord_Type v_MyRecord := omit;<br />
<br />
v_MyRecord.field1 := 1;   // assignment 1<br />
v_MyRecord.field2 := 2;   // assignment 2<br />
<br />
-&gt; It does not make any use to get a run-time error between assignment 1 and 2.<br />
<br />
=&gt; Clause 15.6.2 shall be enhanced to cope with &quot;template (omit)&quot; variables so that internal expansion rules of the core language do not violate the core language itself.<br />
The simplest solution would be to consider fields not being assigned yet as &quot;uninitialized&quot; in terms of isbound (or optional fields could be expanded to omit as well).</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;CR6699_v1.docx (14,648) <span class="italic">09-04-2014 15:12</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=2982&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">06-03-2014 12:19</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=455">Wolfgang Seka</a></td><td class="print">New Issue</td><td class="print"></td></tr><tr class="print"><td class="print">08-04-2014 08:59</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=127">Gyorgy Rethy</a></td><td class="print">Project</td><td class="print">TTCN-3 Change Requests =&gt;
