DOCBOOK: Paragraph indenting problem.

I'm writing a book where I need to indent the first line of every
paragraph in 1.0cm. I'm using, at my stylesheet, this command:

(define %para-indent-firstpara%
  1cm)

(define %para-indent%
  1cm)

(the information below might be useless, but...)
As I don't want the body indented from the titles of chapters,
sections and the rest, I'm also using 

(define %body-start-indent%
  0mm)

The problem is: my paragraphs starts with no indentation. How can I
solve this problem? Am I missing something?

Thanks,
