Following the first submission at [1], the W3C Math Working Group is submitting a revised version of the application/mathml+xml media type registration. This version removes the charset parameter, considered dangerous as prone to conflicts with XML encoding declaration, and corrects a typo in the draft.

Froumentin INTERNET DRAFT W3C draft-froumentin-mathml-media-type-01.txt October 2003 The application/mathml+xml Media Type Status of this Memo This document is anhttp://www.ietf.org/rfc/rfc2026.txt Internet-Draft and is subject to all provisions of Section 10 of RFC2026. http://www.ietf.org/rfc/rfc2026.txt Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents ashttp://www.ietf.org/rfc/rfc2026.txt Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet- Drafts as reference material or to cite them other than as "work in progress."

MathML is an XML application for describing mathematical notation and capturing both its structure and content. Expires: March 2004 1. Introduction The World Wide Web Consortium has issued the specification [MATHML] defining the Mathematical Markup Language (MathML). This memo provides information about the application/mathml+xml Media Type, intended to be used for transferring MathML 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]. This document was prepared by members of the W3C Math working group. Please send comments to www-math@w3.org, a public mailing list with archives at <http://lists.w3.org/Archives/Public/www-math/>. 2. Registration of MIME media type application/mathml+xml MIME media type name: application MIME subtype name: mathml+xml Required parameters: none Optional parameters: none Encoding considerations: See Section 4 of this document. Security considerations: See Section 7 of this document. Interoperability considerations: MathML [MATHML] specifies user agent conformance rules that dictate behaviour that must be followed when dealing with, among other things, unrecognized elements. Published specification: MathML is now defined as a W3C Recommendation; the latest published versions is at [MATHML]. Applications which use this media type: Some content authors have already begun hand and tool authoring on the Web with MathML. However that content is currently described as "text/xml" or "application/xml", allowing existing Web browsers to process it without reconfiguration for a new media type. This new type is being registered in order to allow for the expected deployment of MathML on the World Wide Web, as a first class XML application where authors can expect that user agents are conformant XML 1.0 [XML] processors. Additional information: Magic number: There is no single initial byte sequence that is always present for MathML files. However, Section 5 below gives some guidelines for recognizing MathML files. See also section 3.1 in [XMLMIME]. File extension: There most common file extension that is currently in use for MathML is ".mml". Macintosh File Type code: TEXT Person & email address to contact for further information: Max Froumentin <mf@w3.org> Intended usage: COMMON Author/Change controller: The MathML specification is a work product of the World Wide Web Consortium's Math Working Group. The W3C has change control over these specifications. 3. Encoding considerations By virtue of MathML content being XML, it has the same considerations when sent as 'application/mathml+xml' as does XML. See [XMLMIME], section 3.2. 4. Recognizing MathML files All MathML documents will have the string "<math" near the beginning of the document. Some will also begin with an XML declaration which begins with "<?xml", though that alone does not indicate a MathML document. 5. Charset default rules By virtue of all MathML content being XML, it has the same considerations when sent as 'application/mathml+xml' as does XML ([XMLMIME], section 3.2) in the absence of the charset parameter. 6. Security Considerations The considerations for 'application/xml' as specified in [XMLMIME], also hold for 'application/mathml+xml'. In addition, several MathML instructions may cause arbitrary URIs to be dereferenced. In this case, the security issues of RFC1738, section 6, should be considered. Furthermore, because of the extensibility features that MathML defines, it is possible that 'application/mathml+xml' may describe content that has security implications beyond those described here. However, if the user agent follows the user agent conformance rules in [MATHML], this content will be ignored. Only in the case where the user agent recognizes and processes the additional content, or where further processing of that content is dispatched to other processors, would security issues potentially arise. And in that case, they would fall outside the domain of this registration document. 7.
