RSS is a family of web feed formats written in XML and used in content syndication by enabling applications like RSS readers to find out when new information is available on a website.
Since creation of output from DITA source files is automated by using Ant, it is possible to create or update RSS information about the output at the same time the output is produced. The RSS file can then be uploaded along with the output so its availability can be known to those subscribed to the RSS feed.
