Step 4: Enter the Create URL Document Step
In the Create URL Document step customizer window, in the separate selection boxes, select the string variable uri and the document variable DEFAULT_DOC_VER3 that you created and click OK. This assigns the URL address in the string variable to the document variable.
This step defines the XML document variable, uri, to be used in your script for specifying the VoiceXML document that you will run in the script.
The Create URL Document step does not issue a HTTP request. The request occurs when the document variable is used by another step, such as the Send Response step or the Send JSP step, or, as in our example script, the VoiceBrowser step.

In this example, parameters are not used. If you use parameters, they are passed to the web server where the VXML document is located for use by the web server.
