Hi, I strongly support this generic capabilities work. IMO this approach would make NMDA much easier for a client to support, since the new /yang-library would not be needed for this purpose. Instead, a simple "nmda-operational" capability could be used in this module to easily identify which config=true nodes should be expected in <operational>. The complexity in /yang-library might be justified if new writable datastores (like <ephemeral>) are ever introduced, but not for solving the problem "what features does this server support for the specified data node (resource)"?
