urn:ietf:params:xml:ns:carddav:supported address data

###Purpose

Specifies what media types are allowed for address object resources in an address book collection.

###Protected

MUST be protected as it indicates the level of support provided by the server.

###COPY/MOVE behavior

This property value MUST be preserved in COPY and MOVE operations.

###Allprop behavior

SHOULD NOT be returned by a PROPFIND DAV:allprop request.

###Description

The CARDDAV:supported-address-data property is used to specify the media type supported for the address object resources contained in a given address book collection (e.g., vCard version 3.0). Any attempt by the client to store address object resources with a media type not listed in this property MUST result in an error, with the CARDDAV:supported-address-data precondition (Section 6.3.2.1) being violated. In the absence of this property, the server MUST only accept data with the media type "text/vcard" and vCard version 3.0, and clients can assume that is all the server will accept.
