+    "This module defines configuration and operational state data
+    relating to policy-based forwarding. Policy-based forwarding is
+    utilised when a system chooses how to forward packets (including
+    applying data-plane operations such as encapsulation or
+    decapsulation) based on policies other than destination L2 or L3
+    header. Typically, systems may implement:
+
+     - IP policy-based routing, where routing may be done based on the
+       source plus destination of an IP packet; information within the
+       L4 header; or some combination of both.
+     - Encapsulation or decapsulation based on certain policy
+       information - for example, matching particular IP destinations
+       and decapsulating GRE headers.
+     - Class-based selection of egress routes - such as class-based
+       selection of an egress MPLS path.
+
+    The policies that are defined in this model are applied to a
+    particular ingress context of a network element (e.g., interface)
+    and are defined to apply following other interface policy such as
+    QoS classification and access control lists.
+
+    This module defines:
+
+     - policy-forwarding

+    |--- policies
+    |    |-- policy
+    |        |-- [match criteria]    How packets are defined to
+    |        |                       match policy.
+    |        |-- [forwarding-action] How packets matching should
+    |                                 be forwarded.
+    |--- interfaces
+    |    |-- interfaces
+    |        | -- apply-forwarding-policy  Forwarding policy to
+    |                                      used on the interface.
+    |--- path-selection-groups
+         |-- path-selection-group     A group of forwarding resources
+                                      that are grouped for purposes
+                                      of next-hop selection.
+
+    A forwarding-policy specifies the match criteria that it intends
+    to use to determine the packets that it reroutes - this may
+    consist of a number of criteria, such as DSCP. The action of the
+    policy results in a forwarding action being applied to matching
+    packets. For example, decapsulating the packet from a GRE header.
+    In order to enact the policy based on particular interfaces - the
+    forwarding-policy is applied to an interface via referencing it
+    within an 'apply-forwarding-policy' statement associated with an
+    interface.
+
+    In some cases (e.g., Class-Based Tunnel Selection) the forwarding
+    action does not resolve to a single egress action, and rather
+    normal forwarding rules are to be applied but considering a subset
+    of forwarding resources. In these cases, a path-selection-group
+    can be created, referencing the subset of forwarding paths that
+    should be used for the egress selection. In the case that a subset
+    of MPLS LSPs are eligible for, say, DSCP 46 marked packets, a
+    path-selection-group is created, referencing the subset of LSPs.
+    The forwarding action of the corresponding policy is set to
+    PATH_GROUP and references the configured group of LSPs.";
