The IESG has approved a request to register the "application/oxps." The IESG contact person is Pete Resnick. Type name: application Subtype name: oxps Required parameters: N/A Optional parameters: N/A Encoding considerations: binary Security considerations: OpenXPS uses ZIP compression as specified in .ZIP File Format Specification from PKWARE, Inc., version 6.2.0 (2004). ZIP compressed XML requires parsing untrusted XML data and untrusted ZIP data. The consumer is responsible for validating the .zip archive, the XML structure, and the resource content. Per spec, there should be no active content provided as part of the OpenXPS format. The consumer must ensure that no malicious active content is erroneously provided in the OpenXPS document. Valid content is described in the EMCA-388 specification (http://www.ecma-international.org/publications/standards/Ecma-388.htm). Especially take note of section E.3, which describes steps that can be taken to validate the contents of the payload. Interoperability considerations: application/oxps documents are specified by the XML schemas standardized in ECMA-388. Applications and drivers currently producing/consuming Microsoft XPS content cannot directly produce/consume OpenXPS. Changes are required to address differences in the two specifications, such as namespace, print ticket usage, use of JPEG XR, etc. To ensure interoperability, the clipboard format must be a complete OpenXPS file with .oxps extension. Published specification: The published standard ECMA-388 is available at: http://www.ecma-international.org/publications/standards/Ecma-388.htm Applications that use this media type: The application/oxps MIME type can be used to identify CSTA XML (ECMA-388) instance documents. No published applications or print drivers currently use OpenXPS. The intent is for any application or driver that can currently produce/consume Microsoft XPS to also adopt OpenXPS. Examples of such applications would include but are not limited to: Microsoft XPS Viewer, Microsoft XPS Document Writer, Microsoft Internet Explorer 9. Additional information: Magic number(s): ZIP archive CRC-32: 504b 0304 per http://www.pkware.com/documents/APPNOTE/APPNOTE-6.2.0.txt. Note that is it a requirement of the consumer to ensure that the contents of the ZIP archive is a valid OpenXPS structure.
