Registration of media type application/its+xml

[Felix Sasaki]

MIME media type name:
    application

MIME 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 specifications:
    http://www.w3.org/TR/2007/REC-its-20070403/

Applications which use this media type:
    This new media type is being registered to allow for deployment of ITS
1.0 on the World Wide Web.

Additional information:
    File extension:
        its
    Fragment identifiers:
        A syntax identical to that of "application/xml" as described in IETF
RFC 3023.
    Base URI:
        As specified in IETF RFC 3023, section 6.
    Macintosh File Type code:
        TEXT
    Person and email address to contact for further information:
        World Wide Web Consortium <web-human at w3.org>

    Intended usage:
        COMMON

    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.
