Yes, sorry about that, the documentation is a bit sketchy. I've added 
that to my documentation list.

We don't do any recursive crawling in the TDS (users end up stepping 
through one collection level at a time) and, as you say, it looks like 
all our tests are for single level catalogs. I believe that some of our 
code uses DirectoryScanner to build multilevel catalogs. So, hopefully 
you won't run into any bugs in the building of multilevel catalogs. Let 
me know if you do.
