Internet Engineering Task Force (IETF) H. Thompson Request for Comments: 7303 University of Edinburgh Obsoletes: 3023 C. Lilley Updates: 6839 W3C Category: Standards Track July 2014 ISSN: 2070-1721 XML Media Types Abstract This specification standardizes three media types -- application/xml, application/xml-external-parsed-entity, and application/xml-dtd -- for use in exchanging network entities that are related to the Extensible Markup Language (XML) while defining text/xml and text/ xml-external-parsed-entity as aliases for the respective application/ types. This specification also standardizes the '+xml' suffix for naming media types outside of these five types when those media types represent XML MIME entities.
