Re: [docbook-apps] Hard page break in DocBook 4 document with namespace-aware DocBook XSL stylesheets

["Bob Stayton" <bobs@sagehill.net>]

Hi,
This turns out to be a deficiency in the handling of non-namespaced 
documents by the namespace stylesheets.  The same thing occurs when 
processing a namespaced document with the non-namespace stylesheets.

In order for the namespace stylesheets to handle a non-namespaced document, 
it first preprocesses the document to generate an internal copy of the 
document with the namespace added to all elements.  Then the stylesheet 
processes that copy, using its templates that match elements in the 
namespace.  However, the process of generating the copy currently omits 
processing instructions and comments from the copy.  That's a bug.  If you 
wouldn't mind, could you please file a bug report on the SourceForge site? 
Thanks.
