relcell

The <relcell> element defines a cell in the relationship table (<reltable>). The <topicref> elements that it contains are related to the <topicref> elements in other cells of the same row. By default, topics or resources that are referenced in the same cell are not related to each other, unless you change the collection-type attribute of the <relcell> to indicate that they are related.

Note: These models represent only the default document types distributed by OASIS. Actual content models will differ with each new document type.
