When producing FastTransfer streams for operations configured with RopFastTransferSourceCopy* ROPs, servers SHOULD skip over objects that the client does not have adequate permissions for. For example, if the Move flag of the CopyFlags field, as specified in section, is set, an additional permission to delete an object is required for the object to be included in the output FastTransfer stream. If a permission check for an object fails, the MetaTagEcWarning meta-property (section SHOULD be output in a FastTransfer stream, wherever allowed by its syntactical structure, to signal a client about incomplete content.
