Only by turning your transformation into a multi-phase one in which the
result document of the first phase becomes the input document to the second.

The word "earlier" gives away that you're thinking procedurally. XSLT is a
functional language, the output has to be expressed as a function of the
input, not as a function of things that happened "earlier", because there is
no defined order of execution.
If you can't express the logic as a function of the original input, then use
a multi-phase transformation.
