[xsl] node-id set <-> result document

I am writing an java app that will resolve general queries over a given XML
data source.
I am using Xalan for the XSLT processing.
As I need to do postprocessing of the resulting XML doc, I want the XSL to
return only node ids
representing the result doc instead of an XML document.

I could image Xalan produce a set of node ids for a given XSLT, send it to
my app and later after postprocessing I will give back those node ids and
let Xalan generate a real XML doc out of it.

How can i do that. (generate-id() and id() ???)
