Re: About COPY Overwrite:T Depth:0

Copy with Depth: 0 is one of the fancy ideas of RFC 4918 that was never
seriously defined, just as Collection is mostly undefined.
Copy - with or without Overwrite - of collections only makes sense with
Depths: infinity. Depth 0 or 1 will work when the depth of the tree is
0 or 1 in which case you could use Depth infinity as well. Otherwise
you will get orphaned members or mappings to non-existent members. Or
you create a copy of a collection that isn't a copy because it has a
different list of direct members.
