RE: stds-80220-requirements: Is it a frame or data unit



Title: Message
In the past we have had discussions on "terms to be used".  I want to restart this discussion, because we are using the phrase "Frame Error Rate".  In other 802 documents, we use the term "data units" at the MAC layer.  This is because other standards, like x.25, use the term "frame" to mean information at their layer. 
 
To restart this discussion, I am attaching a diagram that shows how one could decompose a message at layer 7 (or above) to a data unit at layer 2.  I would like to include this diagram in the requirements document, but we do not have a place holder.   I suggest we place this diagram in the appendix with terms.
