Well, it's seriously defined, but maybe it needs to be clarified.

WRT collections: what exactly is the problem?

Depth: 1 isn't defined in 4918.

I'm losing you.

The spec says:

"A COPY of "Depth: 0" only instructs that the collection and its 
properties, but not resources identified by its internal member URLs, 
are to be copied."

The problem I can see is that if you read this literally, you'd copy the 
bindings to the member resources, which is unlikely to be intended. 
Sounds like an erratum to me.

Do you see other problems?
