[xsl] function for getting filename

[Frank Marent <frank.marent@xxxxxxxxxxx>]

i'm struggling again and again over this point:

is there a function in xslt that gives me the clean filename of the  
processed xml file? like

  'myfile.xml'
  'test.xml'
  'anyfilename.xml'

i do *not* need the document-uri. only the filename of the current  
processed xml file.
