[jdom-interest] creating entity definition

[Denis Gaertner]

Hello

I have a problem. I wanna create xml files extracting information from
java objects. I also wanna add references to external xml files using an
external entity. 
How do I achieve an output like this ?

//
  
 <!DOCTYPE mytype SYSTEM "mytype.dtd" [
 <!ENTITY exfile SYSTEM "exfile.xml">
 ]>
  
 ...

 &exfile	

//


I think it is not yet implemented in the DOM Specification. Is there an
other solution for this problem without using other methods of referencing
like Xlink

thx

Denis
