Hmmm... Object Oriented Programming Abused. ;-)

This reminds me that when customizing DocBook/XML, you sometimes need to copy 
the entire function (or template as it is called in XSL). Then, you have to 
make a minor change there. So instead of making sure the stylesheets 
themselves have this option somewhere, you need to create duplicate code.

Well, at least the internals of the stylesheets are very stable, but it still 
has a bad taste in the mouth.
