        Builds a CIMInstance based on this CIMClass.  Properties in the

        properties.  The TOINSTANCE flavor is ignored.  Because the CIM
        specification is unclear on the meaning of this parameter and its
        relationship to instance operations, the behavior when this parameter
        is true MAY change in the future based on clarifications of the
        CIM specification.

        @param includeClassOrigin A Boolean indicating whether ClassOrigin
        attributes are to be transferred from the class object to the
        instance.

        @param propertyList A CIMPropertyList defining the properties that
        are to be added to the created instance.  If the propertyList is not
        NULL, properties defined in the class and in this propertyList are
        added to the new instance.  If the propertyList is NULL, all
        properties are added to the instance.  If the propertyList is empty,
        no properties are added.  Note that this function does NOT generate
        an error if a property name is supplied that is NOT in the class;
        it simply does not add that property to the instance.
