How do you know it doesn't work? In which manner does it fail to work?

Just glancing at it, it looks syntactically incorrect. Are you getting syntax errors at some point?

I believe that w3.org has a DTD validator. Have you tried running it through that? Did you fix the error messages it showed you?
