The RSS 2.0 specification describes how to create RSS documents.
This profile is a set of recommendations for how to create RSS documents that work best in the wide and diverse audience of client software that supports the format.
It's possible that it's simply a placeholder for future development. In a nutshell, when software is available for download (security updates, for example), the download begins on all targeted systems on a network.
When new updates become available, we'll get a chance to test how it works – or if it does actually work this time around.If the connection to the Internet (Cloud) goes down, no worries, all the important bits are already stored locally and delivery can continue unabated.This type of functionality eliminates the need for sole purpose servers, minimizes bandwidth, and decreases reliance on being connected to the Cloud. Others have been doing it successfully for almost a decade.RSS documents can be tested for validity in the RSS Validator.In this document, the key words are to be interpreted as described in RFC 2119.
