2.2.3 Depth "noroot" Request Header Extension

 This header extension is defined as follows, using the ABNF syntax defined in [RFC4234] section 2.1:

 Depth = "Depth" ": " ("0" / "1" / "infinity" / "1,noroot" / "infinity,noroot")

The following values are associated with the Depth header.

Value	Meaning
0	The command applies only to the specified resource.
1	The command applies to the specified resource and the next level of resources that it contains.
infinity	The command applies to the specified resource and all the resources that it contains.
1,noroot	The command applies to the next level of resources in the container but not to the container itself.
infinity,noroot	The command applies to all the resources in the container but not to the container itself.

The noroot extension is present if the "1,noroot" value is set or if the "infinity,noroot" value is set.<3>
