RFC 3744: ACL method and unsupported property principal

Hi,

Can a server limit the set of properties that may be used
to
denote a principal in a principal element? If yes, what
pre-condition
violation should be reported when an unsupported property is
included?

Regards,

Werner.

Only the full ACL can be rewritten. See thr subsequent
paragraph 
(<http://greenbytes.de/tech/webdav/rfc3744.ht
ml#rfc.section.8.1.p.4>):

"Implementation Note: Two common operations are to add
or remove an ACE
from an existing access control list. To accomplish this, a
client uses
the PROPFIND method to retrieve the value of the DAV:acl
property, then 
parses the returned access control list to remove all
inherited and 
protected ACEs (these ACEs are tagged with the DAV:inherited
and 
DAV:protected XML elements). In the remaining set of
non-inherited, 
non-protected ACEs, the client can add or remove one or more
ACEs before 
submitting the final ACE set in the request body of the ACL
method."
