+ * Reference RFC 6020.
+ *
+ * The "grouping" statement is used to define a reusable block of nodes,
+ * which may be used locally in the module, in modules that include it,
+ * and by other modules that import from it. It takes one argument,
+ * which is an identifier, followed by a block of sub-statements that
+ * holds detailed grouping information.
+ *
+ * The "grouping" statement is not a data definition statement and, as
+ * such, does not define any nodes in the schema tree.
+ *
+ * A grouping is like a "structure" or a "record" in conventional
+ * programming languages.
+ * Once a grouping is defined, it can be referenced in a "uses"
+ * statement. A grouping MUST NOT reference itself,
+ * neither directly nor indirectly through a chain of other groupings.
+ *
+ * If the grouping is defined at the top level of a YANG module or
+ * submodule, the grouping's identifier MUST be unique within the
+ * module.
+ *
+ * A grouping is more than just a mechanism for textual substitution,
+ * but defines a collection of nodes. Identifiers appearing inside the
+ * grouping are resolved relative to the scope in which the grouping is
+ * defined, not where it is used. Prefix mappings, type names, grouping
+ * names, and extension usage are evaluated in the hierarchy where the
+ * "grouping" statement appears. For extensions, this means that
+ * extensions are applied to the grouping node, not the uses node.
+ *
+ * The grouping's sub-statements
+ *
