12.7.3 Recursive sections

DocBook exporter exports Org files as articles using the article element in DocBook. Recursive sections, i.e., section elements, are used in exported articles. Top level headlines in Org files are exported as top level sections, and lower level headlines are exported as nested sections. The entire structure of Org files will be exported completely, no matter how many nested levels of headlines there are.

Using recursive sections makes it easy to port and reuse exported DocBook code in other DocBook document types like book or set.
