To direct DITA2Go to include an ID attribute in each instance of an interpolated parent of an element mapped from a particular paragraph format:
[DocBookParentIDs]
; para format = single parent element for which the ID
; of the para should be used.
ParaFmt = ParentElement
When you assign a parent element in [DocBookParentIDs], DITA2Go includes in the specified interpolated parent of each element mapped from ParaFmt the ID attribute assigned (or that would have been assigned) to that element in [DocBookParaIDs]. The ID attribute is added only if the parent is interpolated by DITA2Go as a required ancestor of the current element. Because IDs must be unique, an automatically assigned parent ID disables any Yes setting for the same format in [DocBookParaIDs]; see §26.4.4.2 Providing IDs for block elements. And it also eliminates any ID assigned to the child via DocBookElemID PI marker; see §26.4.4.4 Specifying an ID for an individual block element or parent.
You can override the value of an automatically assigned parent ID attribute with a DocBookParentID PI marker inserted in the child paragraph; see §26.4.4.4 Specifying an ID for an individual block element or parent.
