Currently we have articles.ent and books.ent, and
for example, articles.ent can be used by putting the
following lines in the doctype declaration:
<!ENTITY % articles.ent PUBLIC
"-//FreeBSD//ENTITIES DocBook FreeBSD Articles Entity Set//EN">
%articles.ent;
This pulls all of the necessary entities via share/sgml/articles.ent.
The translation teams can customize these entities by redefining
the articles.ent file in <langcode>/share/sgml. See
ja_JP.eucJP/share/sgml for example.
