Abstract
This document standardizes five new media types -- text/xml,
application/xml, text/xml-external-parsed-entity, application/xml-
external-parsed-entity, and application/xml-dtd -- for use in
exchanging network entities that are related to the Extensible Markup
Language (XML). This document also standardizes a convention (using
the suffix '+xml') for naming media types outside of these five types
when those media types represent XML MIME (Multipurpose Internet Mail
Extensions) entities. XML MIME entities are currently exchanged via
the HyperText Transfer Protocol on the World Wide Web, are an
integral part of the WebDAV protocol for remote web authoring, and
are expected to have utility in many domains.
Major differences from RFC 2376 are (1) the addition of text/xml-
external-parsed-entity, application/xml-external-parsed-entity, and
application/xml-dtd, (2) the '+xml' suffix convention (which also
updates the RFC 2048 registration process), and (3) the discussion of
"utf-16le" and "utf-16be".
