<ibid>
The <ibid> tag is an inline bibliographic marker meaning “the same source as
the previous citation.” It is typically used inside a raw <biblio>
entry when successive references repeat the same work.
Because it depends on the preceding entry, <ibid> only makes sense in a
bibliographic context.
