17 * Constants related to {@code ietf-yang-library.yang}. As schema-mount works in concert with yang-library, we need
18 * these constants to interpret correctly categorize incoming data and present them to schema resolution process.
21 * While RFC7895 and RFC8525 are not strictly required by YANG, RFC7950 contains a weak reference to it when dealing
22 * with capability negotiation on protocol layers. Moreover RFC8528 makes it explicit that an instance of yang-library
23 * is mounted underneath both {@code inline} and {@code shared-schema} types of mount.
26 * While we could mandate use of either RFC7895 or RFC8525 across the board, this is not feasible, as mount points may
27 * be nested and point to external systems -- hence it is completely possible to encounter both old and new information
28 * in a single mount point tree.
