Thanks for the reply. Sadly I can't remember the XML parser version, I
was too eager to get the repository working again. 

I did debug it and you are right the were no namespace declaration
attributes at all. At this point I e-mailed the forum.

Anyway thanks for looking at the DTD, although it clearly wasn't the
problem it did add some confusion.

Good to know that you already found a workaround to this problem. Here's
some thoughts of what might be the cause.

It seems as if the xmlns:nt namespace setting is not being read by the
nodetype reader. The reader code reads all xmlns:* attributes from the
root element of the nodetype configuration file and uses them to set up
the namespace mappings.

I recall a problem in some XML parser implementation that loses the
namespace declaration attributes when using the standard DOM access
methods. This was a somewhat controversial issue (should the namespace
attributes be visible?), but I think the correct answer was that they
should be for standard DOM-level access.

I suspect that this is the cause of your problem, especially as you were
able to fix it by cleaning up the classpath. Can you recall if you had
any specific XML parser implementations on the classpath?

It could well be that the XML file no longer conforms with the inline
DTD included at the beginning of the file. The file is never validated
against the DTD when it is accessed by Jackrabbit. I'll investigate this
and commit a fix if I find the problem.
