(last updated 2011-02-25) Name : MURATA Makoto Email : eb2m-mrt&asahi-net.or.jp MIME media type name : Application MIME subtype name : Vendor Tree - vnd.openxmlformats-officedocument.presentationml.template Required parameters : None. Optional parameters : None. Encoding considerations : binary This media type may require encoding on transports not capable of handling binary. Security considerations : This subtype is intended for an OOXML document of the category Presentation. It is a ZIP package containing OPC parts, some of which are XML documents. An OOXML document of this subtype does not contain macros. Note that different file extensions are used depending on whether OOXML documents contain macros. For example, "potx" is used for macro-free presentation templates, while "potm" is used for macro-enabled presentation templates. An OOXML document of this subtype may contain an Active-X control only when an OPC part of type application/vnd.ms-office.activeX+xml exists within this OOXML document. An OOXML document of this subtype may contain executable contents other than macros or Active-X controls, since the the underlying technology, namely ISO/IEC 29500-2 (Open Packaging Convention) and ZIP, allow such contents. However, such executable contents are beyond ISO/IEC 29500-1 (Fundamentals and Markup Language Reference) and ISO/IEC 29500-4 (Transitional Migration Features). Such executable contents are not invoked by MS Office and similar office suites. An OOXML document of this subtype may contain personal information, but cannnot be encrypted. In other words, ISO/IEC 29500 or Ecma-376 do not provide any mechanisms for encryption. OOXML documents encrypted by mechanisms beyond ISO/IEC 29500 are not of this subtype. An OOXML document of this subtype may contain a digital signature, as specified in ISO/IEC 29500-2. Interoperability considerations : ISO/IEC 29500 has two conformance classes: 'strict' and 'transitional'. This subtype applies to both classes. Some application programs can handle one of them only. Part 3 (Markup Compatibility and Extensions) of ISO/IEC 29500 defines mechanisms for user- or vendor-defined extensions. Even when an OOXML document contains such extensions, application programs are guranteed to work reasonably well as long as it correctly implement Part 3.
