anchor block to bottom of page? (footnote margin problem)

[phillip rhodes]

I am trying to have a fo block be anchored from the bottom of the page.    Basically it's a image, and some text that I want to have appear as far done the page as possible, but not to cause a page break.   I see people use a footnote for this, but this is not working for me. The margins of the footnote are not the same as the calling region (the region that I define my footnote in, which is xsl-region-body)   This is not static text.  It's just a grouping of content that I want as far down as possible on the page.     Can someone point me in the right direction?  Thanks!
