However, it is not obvious what would happen if this value is used in the communication operations. In my opinion there are two options:<br />
<br />
1. It will produce an error.<br />
2. It will work: in case of outgoing operation, no address will be passed to the SA (the corresponding field of the TRI operation will be null). It would be just a more verbous variant of outgoing operations without a to clause. In case of an incoming operation, using null in the from clause would mean that the event can be accepted only if the SA didn't supply any address. (This is different than omitting the from clause as the sender address is not matched in this case).</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;CR6718_resolution_v1.docx (94,500) <span class="italic">06-10-2014 16:38</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3085&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/zip.gif" alt="zip" />&#160;Operational-Semantics-CR6718.zip (1,618,357) <span class="italic">07-10-2014 14:07</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3096&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">09-04-2014 13:44</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=659">Tomas Urban</a></td><td class="print">New Issue</td><td class="print"></td></tr><tr class="print"><td class="print">18-06-2014 08:38</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;
