Re: [xsl] [FO] image on even, table on odd, repeating image if the table is more than one page

What about creating a header area on the even pages to allow both the real 
header and the image?  The OP's original question specified one image per 
table, so a reference to the url() could specify the image associated with 
the table.  (We do something similar with "This page intentionally left 
blank" centered on the blank pages.)
