1.4 Relationship to Protocols and Other Structures
This file format is an OLE compound file as described in [MS-CFB]. It is dependent on the structures described in the following references:
[MS-ODRAW] for the persistence format for shapes.
[MS-OVBA] for the persistence format for a VBA project.
[MS-OFFCRYPTO] for the persistence format for document signing, information rights management, document encryption and obfuscation.
[MS-OSHARED] for the persistence format for additional common structures.
This file format has been superseded by [ECMA-376] in Microsoft Office PowerPoint 2007 and by [ISO/IEC29500-1:2012] in Microsoft PowerPoint 2010 and Microsoft PowerPoint 2013.
