association: An <item name=”association”> element is added to the replacement-data document if the <mail> element has an <association> element child, or if the Subscriber returns an <add-association> element. The content of the <item> element is the association value for the eDirectory object that is associated with the e-mail message being processed. The association value might not yet be written to the eDirectory object; therefore, the association value cannot be used in queries.

url: The content of the <item> element is the complete URL to be used in the e-mail message. On the Subscriber channel, the url item is created from the following items found under the <url-data> element: scheme, host, port, file, and the items underneath the <url-query> element. If scheme, host, or port are not found, then default values are used. The default values are determined from the configuration of the Publisher channel Web server.

url-base: The content of the <item> element is the portion of the generated URL not including the resource identifier (file) and not including the query string.

url-query: The content of the <item> element is a URL query string generated from <item> elements underneath the <url-query> element.

url-file: The content of the <item> element is the resource identifier for the URL.

protected-data: The content of the <item> element is an encrypted form of name-value pairs obtained from <item> elements under the <url-query> element. Only <item> elements whose protect attribute is set to “yes” are added to the protected data value. See Section B.1, Data Security.
