Destination Names
A destination name is a string divided into elements, each element separated by the dot character (.). The dot character allows you to create multi-part destination names that categorize destinations.
For example, you could have an accounting application that publishes messages on several destinations. The application could prefix all messages with ACCT, and each element of the name could specify a specific component of the application. ACCT.GEN_LEDGER.CASH, ACCT.GEN_LEDGER.RECEIVABLE, and ACCT.GEN_LEDGER.MISC could be subjects for the general ledger portion of the application.
Separating the subject name into elements allows applications to use wildcards for specifying more than one subject. See Wildcards for more information. The use of wildcards in destination names can also be used to define "parent" and "child" destination relationships, where the child destinations inherit the properties from its parents. See Inheritance of Properties.
