A single webform generates a single XML file containing the content complying with your defined XSD. Alongside this same webform you can assign more than one rendition template (XSL or FTL), which can generate more files associated with the web-form instance you just created (e.g. HTML, JSP, or even more XSDs an XMLs). The way you name these renditions is the same as naming (and locating) the main content XML file: Using the 'output path' expression. This output path is effectively a freemarker template, and so is quite powerful.
So one of the templates could have the expression: /${webapp}/one/one.jsp whilst the other one could have the expression: /${webapp}/two/two.jsp
