XslWebMaker makes a static website from XML files.
Specifically, it is website development tool that facilitates your use of XSL (XSLT and XPATH) to transform source XML files into a website of XHTML pages.
The resulting website is "static" in that it can be served from the file system (rather than requiring a web server).
This demo website, as an XHTML result opened from \WebOut, is nothing special to look at. It is a simple scaffold from which unlimited customisations could start. Comparing this result against the \Source is where the value lies: in demonstrating how this all hangs together when driven by XSL (XSLT and XPATH).
The resulting web pages are old-school XHTML 1.1. But it would be trivial to modernize this into (X)HTML 5.
