Encoding considerations : By virtue of ITS 2.0 elements being XML, the same considerations when sent as "application/its+xml" as does XML. See RFC 3023, section 3.2. Security considerations : 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. An ITS 1.0 or ITS 2.0 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 [RFC3986] Section 7 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 and ITS 2.0 permit extensions. Hence it is possible that application/its+xml may describe content that has security implications beyond those described here. Because of these considerations application/its+xml may require integrity protection, either through the use of signing or transport protection mechanisms. Interoperability considerations : Published specification : http://www.w3.org/TR/2007/REC-its-20070403/ and http://www.w3.org/TR/its20/ 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.xml provides an example of a document linking to a file with ITS 1.0 and ITS 2.0 "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 which use this media : This new media type is being registered to allow for deployment of ITS 1.0 and ITS 2.0 on the World Wide Web., e.g. by localization tools.
