### 32.4.4 Content model [TopicFirst] settings

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 §32.4.2 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:

• an element name (single parent)

• an element set name (set of possible parents)

• either of two reserved parent names:

Any | Must be the first child of every possible parent
No | 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 FrameMaker document Mif2Go 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.
