+
+ 18.1 Class 1
+
+ A class 1 compliant resource MUST meet all "MUST" requirements in all
+ sections of this document.
+
+ Class 1 compliant resources MUST return, at minimum, the value "1" in
+ the DAV header on all responses to the OPTIONS method.
+
+ 18.2 Class 2
+
+ A class 2 compliant resource MUST meet all class 1 requirements and
+ support the LOCK method, the DAV:supportedlock property, the DAV:
+ lockdiscovery property, the Time-Out response header and the Lock-
+ Token request header. A class 2 compliant resource SHOULD also
+ support the Timeout request header and the 'owner' XML element.
+
+ Class 2 compliant resources MUST return, at minimum, the values "1"
+ and "2" in the DAV header on all responses to the OPTIONS method.
+
+ 18.3. Class 3
+
+ A resource can explicitly advertise its support for the revisions to
+ [RFC2518] made in this document. Class 1 MUST be supported as well.
+ Class 2 MAY be supported. Advertising class 3 support in addition to
+ class 1 and 2 means that the server supports all the requirements in
+ this specification. Advertising class 3 and class 1 support, but not
+ class 2, means that the server supports all the requirements in this
+ specification except possibly those that involve locking support.
