In addition, clause 7.6.8 specifies that the length of this list &quot;shall not exceed&quot; the number of elements plus one.<br />
<br />
=&gt; The wording according to clause 7.6.8 allows in a template that embed_values contains 0 .. N+1 strings.<br />
<br />
This causes a problem for writing receive templates as in general it is up to codec implementation how many empty strings it adds to embed_values.<br />
<br />
Example: Assuming a &quot;mixed type&quot; with two elements and no embedded text being expected in the received xml document in principle it would be necessary to specify embed_values as<br />
&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;&#160;embed_values := ({}, {&quot;&quot;}, {&quot;&quot;, &quot;&quot;}, {&quot;&quot;, &quot;&quot;, &quot;&quot;})<br />
to cope with all possible variants of codec behaviour.<br />
<br />
In addition, when there is an elem_list it seems that the maximum length of embed_values is even unpredictable.<br />
<br />
NOTE: In practice there is especially the question whether the codec generates '{}' or '{&quot;&quot;}'.<br />
<br />
Conclusion: There shall be a rule for codec implementation not to provide any empty strings at the end of embed_values<br />
=&gt; when there is no embedded text it shall result in embed_values := {}</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;CR7969-1.docx (152,514) <span class="italic">12-08-2020 10:57</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3920&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR7969-2.docx (152,943) <span class="italic">13-08-2020 08:08</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3928&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">27-07-2020 10:17</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">10-08-2020 10:05</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=82">Jens Grabowski</a></td><td class="print">Project</td><td class="print">TTCN-3 Change Requests =&gt;
