That's a class in Saxon 6, which implements XSLT 1.0. I think the most
likely explanation is that you are using an old version of DocBook which
detects that the processor is Saxon and then assumes that it must be Saxon
6. You probably want a newer version of the DocBook stylesheets, one which
recognizes more recent versions of Saxon.
