This trait and its implementing types should be jointly sufficient, along with a WMS 'GetMap'
(or a WMTS 'GetTile' or a WCS 'GetCoverage' etc etc) request to produce a visual layer
(represented more fully by OgcLayer.
This type represents *merely* that there is some backing by which valid OGC layers
can be realized. Its purpose is to provide the appropriate level of abstraction for OGC
services to conveniently reuse the same data about underlying imagery
