When I removed "Checked-in" svn ls failed saying it expected to find
the Checked-in prop. But now that you are casting doubt in my mind,
I'll have to try it again. But if in fact we don't need it, then I do
agree that this would be a better solution.

Agreed - Two propfinds on huge collections would take a while indeed.
I like your solution.
