<p>Thanks!</p>
<p>I had misinterpreted the short metadata 'remarks' at <a
href="https://epsg.org/datum_6326/World-Geodetic-System-1984-ensemble.html">EPSG:6326</a>.
Adding some references here:</p>
<ul>
<li>The 'datum ensemble' concept is <a moz-do-not-send="true"
href="https://docs.opengeospatial.org/as/18-005r4/18-005r4.html#97">defined
by OGC</a>.</li>
<li>More extensive explanation on the WGS84 ensemble (2019) is
(e.g.) at
<a class="moz-txt-link-freetext" href="https://dpipwe.tas.gov.au/land-tasmania/datum-modernisation/web-mapping-and-wgs84-web-mercator">https://dpipwe.tas.gov.au/land-tasmania/datum-modernisation/web-mapping-and-wgs84-web-mercator</a>.
And it is referred in
<a class="moz-txt-link-freetext" href="https://www.iogp.org/blog/epsg/upgrade-of-epsg-dataset-data-model/">https://www.iogp.org/blog/epsg/upgrade-of-epsg-dataset-data-model/</a>.<br>
