If an element must be the first child of its parents, the element is listed here:
[TopicFirst]
; Child element = parents, where child must be the first child of the
; specified parents.
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:
Must not be the first child of any parent; for DITA, this includes elements present in the derived-from topic type that are excluded from the specialized topic type. |
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.
