openoffice and docbook/xml

[hvengel]

I want to use Docbook/xml to manage documentation for a project I am working on. Looking at openoffice it has an option to save documents in docbook/xml format but when I try to save even the simplest documents in in docbook/xml format it fails with an error message that says:

Error saving document Untitles1:
Write Error.
The file could not be written.

What do I have to do to get docbook/xml working in openoffice 2?
