#### 24.5.6 Avoiding invalid ancestries

For the purpose of constructing ancestries, by default DITA2Go treats topic as a synonym for concept, task, reference, glossentry, and any other topic type, and treats body as a synonym for any of the body types, such as conbody. This can cause invalid interpolated ancestries, because DITA2Go might include an element, or wrap an element in a parent, that is not valid for the topic type.

To avoid this problem and direct DITA2Go to treat topic and body as applying only to the generic topic type:

[DITAOptions]
; UseCommonNames = Yes (default, in [DITAParents] and
; in [DITAElementSets], treat "topic" as a synonym for
; concept, task, reference, glossentry, and any other
; topic type, and treat "body" as a synonym for any of
; the body types like conbody), or No (treat topic and
; body as applying only to the generic "topic" type)
UseCommonNames = No

For example, when UseCommonNames=Yes (the default), a paragraph whose format is Body will be allowed as a <body> element n a reference topic, where <body> is not valid.
