    @param context contains security and locale information relevant for the lifetime
        of this operation.

    @param objectName -  The ObjectName input parameter defines the source CIM Object
     *  whose associated Objects are to be returned. This may be either a Class name
     *  or Instance name (CIMObjectpath). 
    
     * @param associationClass - The AssocClass input parameter, if not NULL, MUST be a
     *  valid CIM Association Class name. It acts as a filter on the returned set of
     *  Objects by mandating that each returned Object MUST be associated to the source
     *  Object via an Instance of this Class or one of its subclasses. 
    
     * @param resultClass - if not NULL, MUST be a valid CIM Class name. It acts as a filter
     *  on the returned set of Objects by mandating that each returned Object MUST be
     *  either an Instance of this Class (or one of its subclasses). 
    
     * @param role - , if not NULL, MUST be a valid Property name. It acts as a filter on
     *  the returned set of Objects by mandating that each returned Object MUST be
     *  associated to the source Object via an Association in which the source Object
     *  plays the specified role (i.e. the name of the Property in the Association Class
     *  that refers to the source Object MUST match the value of this parameter). 
    
     * @param resultRole -  If not NULL, MUST be a valid Property name. It acts as a
     *  filter on the returned set of Objects by mandating that each returned Object
     *  MUST be associated to the source Object via an Association in which the
     *  returned Object plays the specified role (i.e. the name of the Property in
     *  the Association Class that refers to the returned Object MUST match the
     *  value of this parameter). 
    
     * @param includeQualifiers - If true, this specifies that all Qualifiers for each
     *  Object (including Qualifiers on the Object and on any returned Properties)
     *  MUST be included as <QUALIFIER> elements in the response. If false no
     *  <QUALIFIER> elements are present in each returned Object. 

    @param includeClassOrigin - If true, this specifies that the CLASSORIGIN attribute
     *  MUST be present on all appropriate elements in each returned Object.
     *  If false, no CLASSORIGIN attributes are present in each returned Object. 
    
     * @param propertyList - If not NULL, the members of the array define one or more
     *  Property names. Each returned Object MUST NOT include elements for any
     *  Properties missing from this list. If the PropertyList input parameter
     *  is an empty array this signifies that no Properties are included in each
     *  returned Object. If the PropertyList input parameter is NULL this specifies
     *  that all Properties (subject to the conditions expressed by the other
     *  parameters) are included in each returned Object.
