/**
* Provides the General HTML Support integration for elements which can behave like sectioning element (e.g. article) or
* element accepting only inline content (e.g. paragraph).
*
* The distinction between this two content models is important for choosing correct schema model and proper content conversion.
* As an example, it ensures that:
*
* * children elements paragraphing is enabled for sectioning elements only,
* * element and its content can be correctly handled by editing view (splitting and merging elements),
* * model element HTML is semantically correct and easier to work with.
*
* If element contains any block element, it will be treated as a sectioning element and registered using
* {@link module:html-support/dataschema~HtmlSupportDataSchemaDefinition#model} and
* {@link module:html-support/dataschema~HtmlSupportDataSchemaDefinition#modelSchema} in editor schema.
* Otherwise, it will be registered under
* {@link module:html-support/dataschema~HtmlSupportDataSchemaBlockElementDefinition#paragraphLikeModel} model
* name with model schema accepting only inline content (inheriting from `$block`).
