White Space and Printing

I have an XSL form that has a fold line in it, 3.25" down from the top margin. 
This is to keep the address separate from the text, so that it can be folded
over, put in a window envelope, and mailed.

Is there any sort of <fo:block> attribute where I can specify how far down the
page said block will print?  I thought initially that space-before.optimum would
be it.

I'm working from a Xerxes/Xalan parser setup.
