DocBook DTD

Hello, all!

I begininig with XML and i'd like to do the things well. By it, i want to use
all standars what it exists today.

I found DocBook and i understand it's a syntax XML to define information about
publications, articles and books among others. But, i don't obtain anywhere the

exact DTD or Schema about DocBook for a publication, article or book.

Where can i obtain it?

Thanks

Best regards since Seville (Spain)
