                        If set to "yes", configures DIFxApp to delete binary files that were copied to the system from the driver
                        store when a driver package was installed. If this attribute is set to "no" or not present, DIFxApp does not
                        remove these files from a system. Note that configuring DIFxApp to delete these files is controlled by the
                        Flags entry value of the component that represents the driver package in the MsiDriverPackages custom table.
                        Setting DeleteFiles to "yes" sets the corresponding bit in the Flags entry value. Setting DeleteFiles to "no"
                        clears the corresponding bit in the Flags entry value. If this attribute is not present, DIFxApp uses a
                        default value of "no".

                    <xs:documentation>
                        Specifies that the DIFxApp CustomActions should force the installation of a new Plug and Play driver
                        on a device, even if the currently installed driver on the device is a better match than the new driver.
                        Specifying 'no' is an excellent way to ensure the DIFxApp CustomActions recognize the Component contains
                        a driver for installation.  The default is null which means the Component does not install a driver via
                        DIFxApp CustomActions. See <html:a href='http://www.microsoft.com/whdc/driver/install/difxtools.mspx'>http://www.microsoft.com/whdc/driver/install/difxtools.mspx</html:a>

                        If set to "yes", configures DIFxApp to install unsigned driver packages and driver packages with missing
                        files. For more information, see "Installing Unsigned Driver Packages in Legacy Mode" earlier in this paper.
                        If this attribute is set to "no" or not present, DIFxApp will install only signed driver packages. Note
                        that configuring DIFxApp to install unsigned drivers is controlled by the Flags entry value of the component
                        that represents the driver package in the MsiDriverPackages custom table. Setting Legacy to "yes" sets
                        the corresponding bit in the Flags entry value. Setting Legacy to "no" clears the bit in the Flags
                        entry value that configures DIFxApp to install unsigned driver packages. If this attribute is not present,
                        DIFxApp uses a default value of "no".

                        Specifies an optional installation sequence number. DIFxApp CustomActions install the driver packages in
                        an installation package in the order of increasing sequence numbers. The same sequence number can be used
                        for more than one driver; however, the order in which packages with the same sequence number are actually
                        installed cannot be determined.
