It seems to me that this issue was never addressed.

As defined right now, the way REPORT is used doesn't seem to be 
compatible with the definition of REPORT in RFC 3253, and the definition 
of the Depth: header field in RFC 4918.

Unless I'm missing something, this will be a problem for any 
implementation that tries to implement the sync report based on a 
generic WebDAV reporting framework.

Best regards, Julian
