If an element must be the first child of more than one possible parent, those parents are defined as a single set, listed in [ElementSets]; see §41.4.2 Content model [ElementSets] settings.

One of the following is assigned to each child element that must be the first child, either of a single parent or of any member of a set of parents:

For any child element listed to the left of the equals sign that is not the first child of a specified parent, when processing your DITA document DITA2Go closes the current parent and opens a new instance of that parent.

Settings in [TopicFirst] are used mainly for lists, and for the DITA <title> element.
