If page number starts from 0, pdf output starts with 1

[CrazyHog]

Hello. For some reason I can only user FOP converter. I have docx file with two or more pages. First page doesn't contain page number. Second page (and may be others) has. Page numeration is set to start with 0, so second page has number 1, third page has 2 and etc. But when I convert docx file to pdf using FOP, resultant pfd file has page number 2 on second page.
Can anyone help how can I workaround this problem?
