I was going to write something related about carddav (still reading it...).

A definition of a WebDAV report absolutely MUST specify the scope of the 
request. So, for Depth:0, it needs to specify whether it affects only 
the resource at the Request-URI, or more. The semantics for Depth:1 or 
Depth:infinity then follow from that.

Specifying that the Depth header should be ignored or should be left out 
is in conflict with how reports work in general and thus makes it 
impossible to share code between various different reports.
