OK. I now believe that subsite (or any package, for that matter) deletion cannot be cleanly done at this time. I've deferred deletion/cleanup to some time in the future.
So, I figure the next best thing is to move/rename the subsite and make it inaccessible. I want to retain the ability to re-use the same subsite name and location on the site map.
Can anyone suggest how I could move (say) /subsite1 to some other site map location? As I said, I want to be able to create a new /subsite1 after the relocation of the old subsite.
Thanks,
Randy
