Another go at lc75 and lc88 language

Note that I have not attempted to address the comments on this list
concerning time stamp or other complex type proposals since they are beyond
the scope of the lc comments.

The value of [message id] uniquely identifies the message.

When present, it is the responsibility of the sender to insure that each
message is uniquely identified.

A receiver MUST treat all messages that contain the same [message id] as the
same message.

If a reply is expected and a back-channel may not be available, [message id]
MUST be present.

No specific algorithm for the generation of unique values of [message id] is
given, however methods such as the use of an IRI that exists within a domain
owned by the sender combined with a sequence satisfies the uniqueness
criteria but may not be the best practice from a security perspective.
