Yes. But it doesn't describe all, you also need the RFC3744 REPORTs  
besides other things:
---snip---
      o  MUST support iCalendar [RFC2445] as a media type for the  
calendar
         object resource format;

      o  MUST support WebDAV Class 1 [RFC2518] (note that [rfc2518bis]
         describes clarifications to [RFC2518] that aid  
interoperability);

      o  MUST support WebDAV ACL [RFC3744] with the additional privilege
         defined in Section 6.1 of this document;

      o  MUST support transport over TLS [RFC2246] as defined in  
[RFC2818]
         (note that [RFC2246] has been obsoleted by [RFC4346]);

      o  MUST support ETags [RFC2616] with additional requirements
         specified in Section 5.3.4 of this document;
---snap---


Anyways what Ralf was actually asking for is the minimal subset of  
CalDAV required to make Sunbird/Lightning and Apple iCal work. Which  
is a highly moving target for the first and the second one requires  
pretty much everything described in RFC3744/RFC4791 :-)
I wonder whether it makes sense to start an effort to track what  
those clients do. Not sure, might be worthwhile. But that is not  
GroupDAV (with GroupDAV the servers have a definite reference on what  
clients *must* do).

Greets,
