Subjects
Rendezvous routing daemons modify message subjects and reply subjects to enable transparent point-to-point communication across network boundaries. This modification does not apply to subject names stored in within message data fields; we discourage storing point-to-point subject names in data fields.
Subjects and reply subjects are parts of a message’s address information—they are not part of the message itself; see also Supplementary Information for Messages in .
