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.
