Question: I am wondering if anyone out there has a good answer as to the best way to Reverse Cascade XML configuration.
What does this mean: I have a web application framework which hosts many portals. Each of those portals has a XML configuration file which defines various configuration values. Each of those sites can also have n number of sub-sites. Each sub-site has its own XML configuration and they inherit the look and feel as well as site structure from the ancestor site but the sub-sites have no knowledge of their ancestor site or its configuration.
Goal: What I need to do is make it so that sub-sites can inherit XML configuration sections from the ancestor site. I am sure there are various ways to accomplish this but I am looking for the most efficient, tried and true example I can find.
