WordprocessingML page break: forcing an *odd* page number?

Hi,

Using WordprocessingML, I'd like to insert a *page break*, but there's a twist:

The new content must start on an *odd* page number, inserting an empty page if neccessary (the motivation being: I print the document on both sides of the paper, and it's nicer if every new chapter starts on an odd page).

Example:

- Chapter 1 is pages 1,2,3 (starting on odd page '1')

- Page 4: empty ('4' is even, so you can't start a new chapter here)

- Chapter 2 is pages 5,6 (starting on odd page '5')

- Chaper 3 is pages 7,8,9,10 (starting on odd page '7' )

Could anyone please tell how to do this?

Thanks very much.
