Strictly speaking: the key definition is not linked to a certain tree before
it is called upon by key(). When key() is used, the context node determines
which document the key() function operates on. If you change that by use of,
When key() is used inside the for-each, it will return nodes from
In theory, this opens up the possibility of redirecting the content of your
node-set variable to a separate (temporary) XML file, and use key() in
combination with document() as described above to have it return the nodes
from you temporary tree.
The use of a temp-file to store the node-set variable in itself can be
considered to be suboptimal, I guess, but just to show that the possiblity
