[xml] Question XML output callback

["Asorokin" <aasorokin ncbi nlm nih gov>]

Hi,
Is it possible to pass my own parameters into xml output callback without
having them declared as globals or static? For example my XSLT script
generate multiple output files and it will be greate to store them in
databse inside some xmlOutputCloseCallback. In this case I have to pass DB
session handler into this callback.

Best wishes,
Alex
