                <div class="command">ant stockquote -Daddurl=http://localhost:8280/services/StockQuoteProxy  -Dmode=customquote</div>

                    Sequence Template can act a reusable function. Here the proxy service reuses
                    template xslt_func which will transform requests with the given xslt local entry
                    key And will log the message before and after. It takes xslt transformation corresponding
                    to local entry key as an argument (for insequence this key is xslt-key-req and out sequence it is xslt-key-back).
                    We use call-template mediator for passing the xslt key parameter to a sequence template.
