[jdom-interest] Entities in JDOM?

EntityRef represents an (unexpanded) entity reference in the document. 
It actually does have a public constructor, but it's probably not what 
you're looking for.

The DocType class exposes an "internal subset" that contains a string 
version of the internal subset you're talking about.  We didn't create a 
full object model for the internal subset because it was non-trivial and 
there wasn't much interest.  You can manipulate the string directly if 
you like.
