2.2.5 Math
Each of the objects added to DrawingML documents MUST be contained by other instances of extensions or MUST make use of extensibility mechanisms from Office Open XML file formats. For compatibility with existing Office Open XML file formats implementations, all of the extensions are integrated into DrawingML through the use of AlternateContent elements as specified in [ISO/IEC29500-3:2015] section 7.5.

p:sp, p:graphicFrame, xdr:sp. or cdr:sp |
The p:sp element is specified in [ISO/IEC29500-1:2016] section 19.3.1.43, p:graphicFrame is specified in [ISO/IEC29500-1:2016] section 19.3.1.21, xdr:sp is specified in [ISO/IEC29500-1:2016] section 20.5.2.29, and cdr:sp is specified in [ISO/IEC29500-1:2016] section 21.3.2.22.
Content of the m element is specified by DrawingML ([ISO/IEC29500-1:2016] section 20.1) and the mathematics OMML ([ISO/IEC29500-1:2016] section 22.1), except as restricted and modified by the following table.
