the class GeodeticObjectParser method parseMetadataAndClose.

/**
 * Parses an <strong>optional</strong> metadata elements and close.
 * This include elements like {@code "SCOPE"}, {@code "ID"} (WKT 2) or {@code "AUTHORITY"} (WKT 1).
 * This WKT 1 element has the following pattern:
 *
 * {@preformat wkt
 *     AUTHORITY["<name>", "<code>"]
 * }
 *
 * <div class="section">Fallback</div>
 * The name is a mandatory property, but some invalid WKT with an empty string exist. In such case,
 * we will use the name of the enclosed datum. Indeed, it is not uncommon to have the same name for
 * a geographic CRS and its geodetic datum.
 *
 * @param  parent    the parent element.
 * @param  name      the name of the parent object being parsed.
 * @param  fallback  the fallback to use if {@code name} is empty.
 * @return a properties map with the parent name and the optional authority code.
 * @throws ParseException if an element can not be parsed.
