17.5.9.2 Starting a new hierarchy after the current block
To open a new element or hierarchy of elements after the current block ends:
; Frame para format = elements to be opened, with any other elements
; nested under them, before the current block element starts.
Use this setting to force opening of elements when [DocBookParents] does not suffice.
For individual cases, you can insert a DocBookOpenAfter marker in the paragraph for the current block element instead, with content the name(s) of the element(s) to open. You can also use a DocBookOpenAfter marker to override a [DocBookOpenAfter] setting when you want to open an element or hierarchy other than what the setting specifies.
