2.1.1379 Part 1 Section 21.1.2.1.1, bodyPr (Body Properties)

a.   The standard specifies that the attributes anchorCtr, forceAA, fromWordArt, and rtlCol have an implied value of off.

Office interprets the attributes anchorCtr, forceAA, fromWordArt, and rtlCol as having an implied value of false.

b.   The standard does not fully describe the process for resolving missing attribute values.

In Office, attributes not specified explicitly within the bodyPr element shall have their values determined by inheritance. Attribute values will be resolved using an applicable ancestor element of the same type as the bodyPr element. The inheritance order in which applicable attribute value shall be applied is as follows:

A corresponding ancestor element which is a child element of the txDef element ("[ISO/IEC-29500-1] §20.1.4.1.28; txDef") of the theme part.

A corresponding ancestor element which is a child element of the lnDef element ("[ISO/IEC-29500-1] §20.1.4.1.20; lnDef") of the theme part.

A corresponding ancestor element which is a child element of the spDef element ("[ISO/IEC-29500-1] §20.1.4.1.27; spDef") of the theme part.

If the value of an attribute is not determined via this process, the default value specified within the bodyPr element shall be used.

PowerPoint uses a corresponding child element which is contained within the corresponding sldMaster element ("[ISO/IEC-29500-1] §19.3.1.42; sldMaster") if the value of an attribute is not determined by this inheritance order. If the corresponding sldMaster element ("[ISO/IEC-29500-1] §19.3.1.42; sldMaster") does not specify the value of the attribute and the value was not determined from the inheritance order, then the default value specified within the bodyPr element shall be used.

Word does not evaluate the rot attribute for text rotation in builds before 15609.10000 (Windows)/65.22080801 (Mac).
