Hello Lisa,

 You're right (read about it in section 14)! Additionally, since
<D:principal-URL> element is an ACL xml element (found it out after Thomas
email), slide is indeed correctly extending the basic dav specification.
Like I said earlier, I will sleep better tonight :)

 Many thanks,
 Miguel

This isn't a RFC2518 conformance problem.  The XML specifications in 
RFC2518 are very careful to show that while certain elements are 
required,  additional elements not defined in RFC2518 MAY appear and 
should be ignored if they're not understood.  That language was 
carefully added to allow implementations to extend WebDAV without 
breaking each other.
