Archivist's Note: This documentation applies to all revisions of the RSS 2.0 specification from version 2.0.1 through version 2.0.10 (the current version). Change notes for versions of the specification that predate the founding of the RSS Advisory Board in 2003 are published by UserLand Software.

2. June 5, 2007: In the Extending RSS section, the words "and attributes" were added twice to clarify this sentence: "A RSS feed may contain elements and attributes not described on this page, only if those elements and attributes are defined in a namespace."
