Dorothy J. Hoskins showed how to use XSLT transformations with a simple XML document to prototype a web site. Her handout and other materials are at: www.resourx.com.
Dorothy Hoskins explained how to create light-weight XML apps with DTDs for quick prototyping in a short development timeframe. You can create different modules (for example in different languages) and try them out in a simple user interface, to determine the final document structure. This is particularly good for multiple user-selectable views, topic maps or similar tools.
"Instead of page-for-page redition, you can create numerous presentation views" for different user groups and needs. Users can create ther own view by selecting details in drop down boxes and the like. It is even possible to track user interaction, which can be used further in design considerations.
