  Hum,

the values are evaluated as XPath expressions in the context of the root
of the target document, exactly like the global variables or parameter
values. So the values can be nodesets, but the current API doesn't allow
to directly pass a subtree. If you use "document()" in the expression it
should be possible to load a node-set dynamically when the parameter is
evaluated.

  I hope this will be sufficient, otherwise it might be possible to
add that functionality, but it would require an API extension I'm afraid.
