Correct, though you can use markers to store the results of calculations
made at transformation time to be retrieved at rendering time.

Correct, it cannot. <xsl:value-of/> is an expression in XSLT and the
*result* of XSLT is passed on to an XSL-FO engine for rendering without any
My first comment is that you can repetitively calculate intermediate totals
from a stream of data, seeding the result in a marker at each stage with
the intermediate total at that stage, and then when the FO engine lays out
a page it can retrieve into static content the first or the last of the
markers from the page to allow you to render that particular intermediate
result (of the very many that you calculate) on the page in which the
Note that XSL-FO *does* have an expression language, but only for property
values and not for displayed values. If you have a complex property value
calculation you can simplify your work by producing an expression in the
property that gets calculated by the FO engine, rather than making
contortions in your XSLT to figure that value out.
I hope this helps.
