DOCBOOK-APPS: Retrieving the name of the processed XML document

Hi,

I am faced with a problem that I hope you will help me solve.
I am using XT to process DocBook XML documents and I want my XSL stylesheet
to be able to retrieve the name of the XML file that is being processed.
Does anybody know how to do that ?

Any pointers would be very much appreciated. Regards,

St廧hane Bline.
