 * Represents data model node to maintain information defined in YANG base.
 *  The "base" statement, which is optional, takes as an argument a
 * string that is the name of an existing identity, from which the new
 * identity is derived.  If no "base" statement is present, the identity
 * is defined from scratch.
 *
 * If a prefix is present on the base name, it refers to an identity
 * defined in the module that was imported with that prefix, or the
 * local module if the prefix matches the local module's prefix.
 * Otherwise, an identity with the matching name MUST be defined in the
 * current module or an included submodule.
