They have one crucial feature external entities don't for me: both
the whole and the part documents can be fully valid documents.
Sometimes I want to publish my whole book. Sometimes I just want to
publish a chapter. Since I'm writing in DocBook with lots of
entities, publishing the chapter requires it to have a DTD and thus a
document type declaration, which prevents it from being an external
parsed entity.
