 ### Alternative Coordinate Reference System support
 
-While the required Coordinate Reference System for any data encoded in GeoJSON is CRS84, a client may request delivery of a data set using a different projected reference system, as per the mechanism described in Requirement 8 in the [WFS 3.0 draft specification](https://github.com/opengeospatial/WFS_FES). 
+While the required Coordinate Reference System for any data encoded in GeoJSON is CRS84, a client may request delivery of a data set using a different projected reference system, as per the mechanism described in Requirement 1 of the [CRS extension](https://github.com/opengeospatial/WFS_FES/tree/master/extensions/crs) of the [OGC API - Features specification](https://github.com/opengeospatial/WFS_FES). 
 
-An INSPIRE Download service delivering data encoded in GeoJSON shall be able to deliver projected geometries if a client requests these explicitly, at least for the spatial reference systems documented in section 6.3. of the data specifications that fall within the scope of this encodign specification. When delivering data that is not in [CRS 84](http://www.opengis.net/def/crs/OGC/1.3/CRS84), the GeoJSON data should include the `crs` member as defined in the deprecated (Draft 6 of the GeoJSON specification)[http://wiki.geojson.org/GeoJSON_draft_version_6].
