Well, it's like the OLE filter. You have one file, containing a kind of file 
system (like a tarball). You need one filter which reads the "file system" 
and passes on the information.

You can do that in two different ways:
- Pass the information around inside the filter, like the OLE filter does it
- Save the "subdocuments" to temporary files and invoke plain filters on them.
  This is the simpler, but slower solution

Both concepts (should) work for import and export.

Ciao,
Werner
