        // Create the WBSAXDocumentOutputter - this serialises the MCSDOM into
        // WBSAX events. This will then be configured for any special
        // processing that it needs to do.

        // Set up the null name element processor.

        // todo: move "final" disassembler here to show accesskeys
        // Otherwise it is too late to capture accesskey output properly and
        // you will see null data in AccesskeyOpaqueValues rather than the
        // appropriate accesskey values which appear in the output (hopefully).
        // This will require refactoring since the "final" disassember is
        // currently cut and pasted below twice (dissection/none).
        // It might be a good idea to add a description to the disassember
        // constructor as well since dissection uses multiple disassemblers in
        // one pipeline.

        // If this protocol supports access key attributes...
        if (supportsAccessKeyAttribute) {
            // ... then set up the special processing for access keys.

            // This is required to calculate access key values when we are
            // using numeric shortcut style menus against WML which, unlike
            // Openwave, does not support this automagically.
            // NOTE: we could slightly improve performance by only doing this
            // when actually required, but whether it is worth calculating this
            // is not clear at this stage.
            //
            // This consists of two parts as outlined below.

            // First, we add a special element processor to the outputter which
            // picks up any special ACCESSKEY-ANNOTATION elements that have
            // been inserted into the MCSDOM by the protocol for each element
            // which uses an accesskey which requires a calculated value and
            // translates them into special opaque WBSAX events during the
            // MCSDOM output phase.

                new WBSAXAccesskeyAnnotationElementProcessor(processorContext,
                                                             !doesDeviceDisplayAccesskeyNums));

            // Second, we add a special filter to the producer which picks up
            // the special opaque WBSAX events created by the element processor
            // above and calculates the appropriate accesskey value as required
            // during the WBDOM output phase. This needs to be done here so
            // that dissection doesn't end up throwing accesskey values away.
            producer = new AccesskeyWBSAXFilter(codec, producer,
                                                wmlConfiguration.getAttributeStartFactory());
        }
