[prog] Including entities in DocBook

[Dan Richter]

I have several DocBook docs that have a lot of entities in common. I would 
like to declare all the entities in a single file, like this:
   <!DOCTYPE ... [
       <!ENTITY entity-file SYSTEM "foo">
       &entity-file;
   ]>
But that doesn't work. Can anyone suggest a way of accomplishing the same 
thing? While we're at it, it would be nice if it worked with XML, not just 
SGML. (Yeah, I know, would you like the moon with that too...)

    said that they prefer attacking Linux systems and very rarely
    target anything running Windows, simply because to do so is
    far too easy...
