## Sending a concept where the coding system and code is unknown 

In the exceptional case that the code is not known, then the <code>code.text</code> element MAY be populated without the need to populate a coding element, as per the example below.

<div class="tab">
 <button class="tablinks active" onclick="openTab(event, 'table-view')">Table View</button>
 <button class="tablinks" onclick="openTab(event, 'tree-view')">Tree View</button>
  <button class="tablinks" onclick="openTab(event, 'xml-view')">XML View</button>
  <button class="tablinks" onclick="openTab(event, 'json-view')">JSON View</button>
</div>

<div id="table-view" class="tabcontent" style="display:block">
  <h3>Table View</h3>
{{table:Extension-UKCore-CodingSCT-CodeUnknown-Example}}
</div>

<div id="tree-view" class="tabcontent">
  <h3>Tree View</h3>
{{tree:Extension-UKCore-CodingSCT-CodeUnknown-Example, expand:9}}
</div>

<div id="xml-view" class="tabcontent">
  <h3>XML View</h3>
{{xml:Extension-UKCore-CodingSCT-CodeUnknown-Example}}
</div>

<div id="json-view" class="tabcontent">
  <h3>JSON View</h3>
{{json:Extension-UKCore-CodingSCT-CodeUnknown-Example}}
</div>
