  Can you run with -v to see what it is trying to do at that point.
Clearly if for some reason the stylesheet ends up with a main output
document and not just chunks, then by specifying a directory libxslt
would try to save to it, and since it's a directory well you would
get those kind of errors.

  Maybe the doctype-* attributes force the presence of a DTD node so
the main document is not empty and you get the error, that does not 
sound wrong. What you want to do is set doctypes for the chunks, and
that should be done on the exslt:document element and not on the
main stylesheet output definition.
