I believe that this summary is generally correct, though it is only the first
step in what the recipient of the message must do. I work on the assumption that
the recipient of the message must perform some processing upon it to derive
whatever his own particular use for that message might be. It is effectively an
implementation detail on the receiving node whether an immediate input to that
process is the message content itself, or some derived semantics or meaning
associated by the sender with that message, to which the recipient can be
pointed by the namespace mechanism. In any case, it is certain that the
recipient, in processing the message will often need to take account of the
sender's semantic understanding of its content, though the sender's intent will
rarely be the recipient's own final understanding of that message.

Respectfully,
