Re: [docbook] Xinclude processing with docbook 5

I checked this out and can confirm that with 
Xerces, any XIncludes that reference an xml:id in the included document don't 
work the same for DocBook 5 documents.  Just to be clear, the issue is not 
the use of the namespace-aware stylesheets, because the XInclude is resolved by 
the XML parser before the stylesheets are applied.  The issue is the 
XInclude function in the Xerces parser.  Such XIncludes work fine with 
xmllint.

 

It seems that in order for the Xerces 
XInclude processor to find an xml:id, it must be informed that an xml:id 
attribute is an attribute of type "ID".    I can get it to work if I 
add a DOCTYPE and reference to the DocBook 5 DTD to the included document.  

 

<?xml version="1.0"?>
<!DOCTYPE book 
SYSTEM "../docbook50/dtd/docbook.dtd" [
<!ENTITY esb "ESB 
stuff">
]>
<book xml:lang="es" xmlns="http://docbook.org/ns/docbook" 
version="5.0">

etc.

That defines the para element's xml:id attribute of 
type ID:

 

<!ENTITY % db.common.attributes 
"
        xml:id  
ID      #IMPLIED

I believe this is a bug in the Xerces XInclude 
processor.  An attribute named xml:id is predefined to be of type ID by the 
standards.  You shouldn't have to identify it as type ID.  It works 
with xmllint without such prompting.

Subject: [docbook] Xinclude processing 
  with docbook 5

  

  
What xinclude 
  processing tools are people using with docbook 5?

  
I'm using the 
  latest xerces with saxon and as soon as I switched from using the namespace 
  unaware stylesheets to the namespace aware stylesheets my xpointer references 
  stopped resolving.

  
Using oXygen 9.2, 
  the xpointers resolve nicely but I need something that can run outside the 
  editor for batch processing.
