# properties.mediaTypes.description
In cases where a property is available only in a subset of the
supported feature encodings, the list of the media types of the
encodings can be specified.

This capabilitiy is also needed for cases where the names of
properties may differ between feature encodings. For example, 
identifiers in an XML/GML encoding may include a namespace, 
in GeoJSON or MVT this is not the case. 

There are other reasons, too. For example, the property identifier
in a Shapefile may be different because of length restrictions.
