          "This module defines configuration and operational state data
    for transceivers (i.e., pluggable optics).  The module should be
    used in conjunction with the platform model where other
    physical entity data are represented.
    
    In the platform model, a component of type=TRANSCEIVER is
    expected to be a subcomponent of a PORT component.  This
    module defines a concrete schema for the associated data for
    components with type=TRANSCEIVER.
    
    A transceiver will always contain physical-channel(s), however
    when a line side optical-channel is present (i.e. ZR+ optics)
    the physical-channel will reference its optical-channel.
    In this case, the optical-channels components must be
    subcomponents of the transceiver. The relationship between the
    physical-channel and the optical-channel allows for multiple
    optical-channels to be associated with a transceiver in addition
    to ensuring certain leaves (i.e. output-power) are not duplicated
    in multiple components.
    
    If a transceiver contains a digital signal processor (DSP), such
    as with ZR+ optics, the modeling will utilize hierarchical
    components as follows:
    PORT --> TRANSCEIVER --> OPTICAL_CHANNEL(s)
    The signal will then traverse through a series of
    terminal-device/logical-channels as required. The first
    logical-channel connected to the OPTICAL_CHANNEL will utilize the
    assignment/optical-channel leaf to create the relationship. At the
    conclusion of the series of logical-channels, the logical-channel
    will be associated to its host / client side based on:
    * If the TRANSCEIVER is directly within a router or switch, then
     it will use the logical-channel ingress leaf to specify the
     interface it is associated with.
    * If the TRANSCEIVER is within a dedicated terminal (Layer 1)
     device, then it will use the logical-channel ingress leaf to
     specify a physical-channel within a TRANSCEIVER component
     (i.e. gray optic) that it is associated with.";
