Wanted to be able to indicate when our WMS layers are also provided as cached map tiles via WMS-C since this improves performance and would benefit end users over the traditional WMS service. While this is not an official OGC specification, I have still labeled it "OGC:WMS-C" since its usage is very related to OGC:WMS and since it can be considered an unofficial profile of WMS (whose recommendations stem from OSGeo). While WMS-C has been superceded by the OSGeo Tile Map Service specification (TMS) and the OGC Web Map Tile Service standard (WMTS), it is still widely supported. This came up in the context of providing ISO 19115 metadata for our GeoServer, whose GeoWebCache integration provides WMS-C.
