[xsl] [xsl-fo] how to suppress footers in a blank page

[Geert Bormans <geert@xxxxxxxxxxxxxxxxxxx>]

Hi,

I am adding a blank page if a chapter in a book starts on an even 
page, using break-before
The footer and header are calculated dynamically with markers and all that
How can I prevent the footer from appearing on the blank page.

I thought of having a conditional page master reference excluding the 
region-before and region-after
But I suspect that I will get an error since I am stuffing things in 
a region that is not defined...

Any suggestions?

Thanks

Geert
