Feilpe,

This is not a FOP problem.

1. Comment out the DocTypeDecl of your chapter document
2. In book document. Change your ent Decl from 
<!ENTITY % bug SYSTEM "bug.xml">
to
<!ENTITY bug SYSTEM "bug.xml">

3. Then validate your book (I don't know which Parser and XSL Processor you 
use, I suggest Xerces/Xalan.)
4. Resolve any validity problems.


Other ideas not related to your problem.
- Is there any reason why you use ISO-8859-1. I recommend UTF-8.
- I suggest placing all ent Decl in a separate file. So your DocTypeDecl will 
look like this:

<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN"
                      "http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd"; [
<!ENTITY % global_entities SYSTEM "global.ent">
%global_entities;
]>

This way you will be able to keep all ent in one place for use by all 
documents.

Hope this helps,
