Re: [docbook] Generating modified 5.0 DTD using mods to RELAX NG version

Hi Bob,

Yes, the DTD for 5.0 was generated from the 
RelaxNG schema by Norm Walsh using automated tools that included Trang, but 
possibly including some other massaging to get it to work.  You might ask 
Norm directly.

Subject: [docbook] Generating modified 
  5.0 DTD using mods to RELAX NG version

  

  
I 
  created an RNG schema modification file, as described at http://www.docbook.org/docs/howto/, 
  and using jing I can validate a demo document against it. 

  
 

  
Next, I tried to create a DTD from my modification file using 
  trang, but got a lot of errors. Even using trang to try to convert 
  docbook-5.0\rng\docbook.rng with no reference to modifications, I get about 
  100 error messages. Most say 'error: sorry, cannot handle this kind of 
  "choice"', but many follow this format:

  
 

  
  sorry, not handled: duplicate declaration of element "info" from 
  namespace "http://docbook.org/ns/docbook"

  
 

  
Were 
  the official distribution DTD versions created using an automated tool, and if 
  so, which one? 

  
 

  
thanks,

  
 

  
Bob
