/**
    This class defines a set of functions that support the manipulation of
    instances of a CIM object class and their properties.

    <p>The Instance Provider is the most common provider, and is the provider
    interface used by the CIM Server to perform instance and property
    manipulation operations.</p>

    <p>The Instance Provider receives operation requests from clients through
    calls to these functions by the CIM Server. Its purpose is to convert
    these to calls to system services, operations on system resources, or
    whatever platform-specific behavior is required to perform the operation
    modeled by the request. The specific requirements for each of the interface
    functions are discussed in their respective sections.</p>
