### 41.4 Understanding content-model configurations

A content-model configuration file includes the following sections:

[Topic] | Lists the root element used to generate the content model. Also includes PUBLIC and SYSTEM identifiers for DITA or DocBook, and the starting topic and body element for DITA topic types. See §41.4.1 Content model [Topic] settings.
[ElementSets] | Groups elements into sets for assignment in sections [TopicParents] and [TopicFirst]. See §41.4.2 Content model [ElementSets] settings
[TopicParents] | Lists the valid parent element(s) of each element. See §41.4.3 Content model [TopicParents] settings.
[TopicFirst] | Lists parent elements for which a given element must be the first child. See §41.4.4 Content model [TopicFirst] settings.
[TopicLevels] | Specifies required levels for certain elements. See §41.4.5 Content model [TopicLevels] settings.
[ElementTypes] | Classifies each element as to whether it is block or inline, whether it allows text, and whether it is preformatted. See §41.6 Inspecting and correcting element types.
