Cascading Stylesheet for DocBook XML

Hi dev,
   I'm Sanjaya Liyanage and a final year undergraduate
student of faculty of Computer Science & Engineering,University of
Moratuwa,Sri Lanka.I would like to hold the "Cascading Stylesheet for
DocBook XML" project as my this year gsoc project.These days I'm
getting familiarised on DocBook and CSS.I will be pleased if anyone can
share anything regards this idea as I don't have a clear idea on what
are the expectations of this idea and what are the goals I must achieve.

Thank you very much,
