Hi folks,

Of particular interest to those interested in XHTML as a supported
source format for IPP Printers.  Also those interested in the MS
UPnP printing effort (which is defining XHTML-Print, an extension
of XHTML-Basic with some CSS formatting).

[here are the Abstract and Introduction verbatim]


   This document defines the "application/xhtml+xml" MIME media type
   for XHTML based markup languages; it is not intended to obsolete
   any previous IETF documents, in particular RFC 2854 which registers

   This document was prepared by members of the W3C HTML working group
   based on the structure, and some of the content, of RFC 2854, the
   registration of "text/html". Please send comments to

1. Introduction

   In 1998, the W3C HTML working group began work on reformulating HTML
   in terms of XML 1.0 [XML] and XML Namespaces [XMLNS].  The first
   part of that work concluded in January 2000 with the publication of
   the XHTML 1.0 Recommendation [XHTML1], the reformulation for HTML
   4.01 [HTML401].

   Work continues in the HTML WG on XHTML Modularization (see
   http://www.w3.org/TR/xhtml-modularization), the decomposition of
   XHTML 1.0 into modules that can be used to compose new XHTML based
   languages, plus a framework for supporting this composition.

   As of December 2000, the HTML WG has taken no official position on
   what MIME media type should be used to describe XHTML 1.0 or any
   other XHTML based language, except in the case where XHTML 1.0
   documents satisfy certain additional requirements (see [XHTML1]
   section 5.1) and can be described with "text/html" (see [TEXTHTML]).

   This document only registers a new MIME media type,
   "application/xhtml+xml".  It does not define anything more than is
   required to perform this registration.  The HTML WG expects to
   publish further documentation on this subject, including but not
   limited to, information about rules for which documents should and
   should not be described with this new media type, and further
   information about recognizing XHTML documents.

   This document follows the convention set out in [XMLMIME] for the
   MIME subtype name; attaching the suffix "+xml" to denote that the
   entity being described conforms to the XML syntax as defined in XML
   1.0 [XML].
