2.2.2 Settings Extensions

The Settings element ([ISO/IEC29500-1:2016] section 17.15.1.78) is extended by the addition of one or more of the following elements: chartTrackingRefBased (section 2.5.1.2), docId (section 2.6.1.14), docId (section 2.5.1.7), conflictMode (section 2.6.1.7), discardImageEditingData (section 2.6.1.13), defaultImageDpi (section 2.6.1.12). To maintain compatibility with ISO/IEC-29500 implementations, the element’s namespace prefix MUST be specified in an Ignorable attribute ([ISO/IEC29500-3:2015] section 7.2).
