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.
