1.3 Overview

This structure provides an extended XML vocabulary for a PresentationML document. The extended elements and attributes allow the format to indicate further information about a document, or content and formatting of parts of the document beyond the elements and attributes described in [ISO/IEC29500-1:2016]. Because these elements and attributes are meant as extensions, their intent and usage varies.

The extensions support new functionality involving slide transitions (section 2.2.1), slide animations (section 2.2.2), content parts (section 2.2.3), media (section 2.2.4), sections (section 2.2.5), slide show (section 2.2.6), images (section 2.2.7), math (section 2.2.8), change tracking (section 2.2.9), comments (section 2.2.10), guides (section 2.2.11), and charts (section 2.2.12).

The extensions in this format are integrated into [ISO/IEC29500-1:2016] by means of the Markup Compatibility and Extensibility features as described in [ISO/IEC29500-3:2015]. Specifically, the Ignorable attribute ([ISO/IEC29500-3:2015] section 10.1.1), the AlternateContent element ([ISO/IEC29500-3:2015] section 10.2.1), and application-defined extension elements are used to maintain compatibility with [ISO/IEC29500-1:2016] implementations when integrating the extensions from this format. Using these extensions as described in this document will result in a PresentationML document that is conformant to [ISO/IEC29500-1:2016].
