Separation of Message Header and Message Body
The design of an EMS is usually broken down into two sections:
- Message header design – Message headers contain the information necessary to route messages. Message headers are usually coded in clear text so that intermediate nodes receive all the necessary information they need to route and prioritize the message. Message headers are analogous to the information printed on the outside of a letter (to, from, priority of message etc.)
- Message body semantics – Message body semantics include the precise definition of all of the data elements in the body of the message. Message semantics can be aided by the use of a precise data dictionary that documents metadata.

Famous quotes containing the words separation of, separation, message and/or body:
“... the separation of church and state means separation—absolute and eternal—or it means nothing.”
—Agnes E. Meyer (1887–1970)
“Just as children, step by step, must separate from their parents, we will have to separate from them. And we will probably suffer...from some degree of separation anxiety: because separation ends sweet symbiosis. Because separation reduces our power and control. Because separation makes us feel less needed, less important. And because separation exposes our children to danger.”
—Judith Viorst (20th century)
“Children in home-school conflict situations often receive a double message from their parents: “The school is the hope for your future, listen, be good and learn” and “the school is your enemy. . . .” Children who receive the “school is the enemy” message often go after the enemy—act up, undermine the teacher, undermine the school program, or otherwise exercise their veto power.”
—James P. Comer (20th century)
“Alas! While your ambitious vanity is unceasingly laboring to cover the earth with statues, with monuments, and with inscriptions to eternalize, if possible, your names, and give yourselves an existence, when this body is no more, why must we be condemned to live and die unknown?”
—Thomas Paine 1737–1809, U.S. writer and magazine editor. Pennsylvania Magazine, pp. 362-4 (1775)
