          "This module defines a data model for representing a system
        component inventory, which can include hardware or software
        elements arranged in an arbitrary structure. The primary
        relationship supported by the model is containment, e.g.,
        components containing subcomponents.
    
        It is expected that this model reflects every field replacable
        unit on the device at a minimum (i.e., additional information
        may be supplied about non-replacable components).
    
        Every element in the inventory is termed a 'component' with each
        component expected to have a unique name and type, and optionally
        a unique system-assigned identifier and FRU number.  The
        uniqueness is guaranteed by the system within the device.
    
        Components may have properties defined by the system that are
        modeled as a list of key-value pairs. These may or may not be
        user-configurable.  The model provides a flag for the system
        to optionally indicate which properties are user configurable.
    
        Each component also has a list of 'subcomponents' which are
        references to other components. Appearance in a list of
        subcomponents indicates a containment relationship as described
        above.  For example, a linecard component may have a list of
        references to port components that reside on the linecard.
    
        This schema is generic to allow devices to express their own
        platform-specific structure.  It may be augmented by additional
        component type-specific schemas that provide a common structure
        for well-known component types.  In these cases, the system is
        expected to populate the common component schema, and may
        optionally also represent the component and its properties in the
        generic structure.
    
        The properties for each component may include dynamic values,
        e.g., in the 'state' part of the schema.  For example, a CPU
        component may report its utilization, temperature, or other
        physical properties.  The intent is to capture all platform-
        specific physical data in one location, including inventory
        (presence or absence of a component) and state (physical
        attributes or status).";
