The animation depicts a request and reponse transaction between client machines, a server, and a WSDL document.
In the animation, a server with Web Services written below it appears on the screen. It then moves diagonally down to the right corner. Next a Markup Language page appears. There is WSDL written above the page. It moves diagonally up to the left corner. Two computers appear at the other two corners. There is Client written next to those computers. Next a set of arrows with Request written next to them emerge from the two computers and point in the direction of the WSDL document. Another set of arrows with Response written next to them appears from the WSDL document and point in the direction of the two client computers. From these client computers a set of arrows with Access written next to them emerge and point in the direction of the Web Services server.
