Re: [docbook-apps] Error in Docbook XSL stylesheets?

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

This is a strange error that I've not seen before.  Those templates have a 
lot of mileage, so I don't think it is a bug there.  Does this occur with 
all documents?  Can you post a very short document that illustrates the 
problem?
