<p>I don't think EPSG extent short names qualify as identifiers.
They might be altered between EPSG releases. Only their EPSG code
is a true (ie unmutable) identifier.<br>

So basically the object model of osgeo::proj::metadata::Extent
should likely be extended with a shortName() getter (the
corresponding GeoAPI class that serves as the inspiration, <a
class="moz-txt-link-freetext"
href="http://www.geoapi.org/3.0/javadoc/org.opengis.geoapi/org/opengis/metadata/extent/Extent.html"
moz-do-not-send="true">http://www.geoapi.org/3.0/javadoc/org.opengis.geoapi/org/opengis/metadata/extent/Extent.html</a>,
has a single getDescription()), a C binding to get it (likely
proj_get_area_of_use_ex2()), and
AuthorityFactory::Private::createPropertiesSearchUsages() be
modified to populate it.</blockquote>
<p>Alternatively if the short area name can be seen as an
identifier, then in ISO 19115 model it can be a
GeographicDescription. That description can then be included
among the values returned by Extent.getGeographicElements().</p>
<p>Note: EPSG defines domain of validity not only by bounding
boxes or by names, but also by polygons stored as Shapefile. The
latter could be returned by BoundingPolygon in ISO 19115 model.
Said otherwise, Extent.getGeographicElements() allows to specify
an area of validity in different ways:</p>
<ul>
<li>By identifier</li>
<li>By bounding box</li>
<li>By bounding polygon</li>
</ul>
<p>Those 3 ways can be made available together.</p>
