Registration of media type application/its+xml

[Felix Sasaki]

Hello Björn, all,

below is a submission with the new template. I tried to implement your
comments (and now with an extended "published specification" section. Please
have a look.

Thanks,

Felix

Subject: Registration of media type application/its+xml

Type name: application

Subtype name: its+xml

Required parameters: none

Optional parameters: charset
This parameter has identical semantics to the charset parameter of the
"application/xml" media type as specified in IETF RFC 3023.

Encoding considerations: Identical to those of "application/xml" as
described in IETF RFC 3023, section 3.2, as applied to an ITS document.

Security considerations: An ITS 1.0 document may cause arbitrary URIs or
IRIs to be dereferenced, via the @xlink:href attribute at the its:rules
element. Therefore, the security issues of [RFC3987] Section 8 should be
considered. In addition, the contents of resources identified by file: URIs
can in some cases be accessed, processed and returned as results. An
implementation of ITS global rules requires the support of XPath 1.0 or its
successor. Hence, processing of global rules might encompass dereferencing
of URIs or IRIs during computation of XPath expressions. Arbitrary recursion
is possible, as is arbitrarily large memory usage, and implementations may
place limits on CPU and memory usage, as well as restricting access to
system-defined functions. ITS 1.0 permits extensions. Hence it is possible
that application/its+xml may describe content that has security implications
beyond those described here.

Interoperability considerations: There are no known interoperability issues.

Published specification: http://www.w3.org/TR/2007/REC-its-20070403/
Any XML document containing ITS 1.0 "its:rules" elements
http://www.w3.org/TR/its/#selection-global can be labeled with
application/its+xml.
http://www.w3.org/TR/its/EX-link-external-rules-2.xmlProvides an
example of a document linking to a file with ITS 1.0 "rules".
The link target is at
http://www.w3.org/TR/its/EX-link-external-rules-1.xml. There is no
need that the link target has "its:rules" as a root element.
The processing semantics is that rules are gathered in document order.

Applications that use this media type: This new media type is being
registered to allow for deployment of ITS 1.0 on the World Wide Web., e.g.
by localization tools.

Additional information:
    Magic number(s): none
    File extension(s): its
    Macintosh file type code(s): TEXT

Person & email address to contact for further information: World Wide Web

Intended usage: COMMON

Restrictions on usage: none

Author / Change controller: The Internationalization Tag Set (ITS) 1.0
specification set is a work product of the World Wide Web Consortium's
Internationalization Tag Set Working Group. The W3C has change control over
this specification.
