You are quite right is saying the a perception is not a model.  But that's
not what I thought I wrote.   I said that I defined analysis as a mapping
**from** some perception **to** a model.   In other words, for me the
analysis process is basically about expressing concepts in a form that can
communicate those concepts.  Does that make sense?
