a. The standard does not fully describe the process for resolving missing attribute values.
In Office, attributes not specified explicitly within this element shall have their values determined by inheritance. Attribute values will be resolved using an applicable ancestor element of the same type as this 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 lstStyle element ("[ISO/IEC-29500-1] §220.127.116.11.12; lstStyle (Text List Styles)") and has a matching paragraph level and is contained within the same package part as the text to which the attribute values shall apply.
If the value of an attribute is not determined via this process, the default value specified within this element shall be used.
PowerPoint uses a corresponding child element which is contained within the corresponding sldMaster element ("[ISO/IEC-29500-1] §18.104.22.168; sldMaster (Slide Master)") if the value of an attribute is not determined by this inheritance order. If the corresponding sldMaster element ("[ISO/IEC-29500-1] §22.214.171.124; sldMaster (Slide Master)") does not specify the value of the attribute and the value was not determined from the inheritance order, then the default value specified within this element shall be used.
