I think there are basically three levels of approaches to providing
different versions of web pages:

    low level    -     information is stored in primary version of web
                       page and extracted as needed

    middle level    -  the source is self-contained and self-configuring
                       and creates different versions of itself depending on
		       desired characteristics

    high level      -  content is stored in something like XML or database
                       and then transformed as needed

The web site developer can choose depending on what skills and resources
are available.
