Yes, that's what it looked like.  Only that the E rather abruptly
appeared for the first time in the enumeration of denotation cases.
That is, something to the effect "For each E that is a well-formed
'piece' etc etc" before the table would have helped.  [Perhaps it
could be added to the explication of interpretations I?  eg. after the
definition, "By I(E) we will mean the interpretation of E where E will
be any well-formed 'piece' etc. etc".]

No ambiguity, just that a statement of why these cases exhaust the
ones of interest would seem more complete.

Truth be told, I'm just observing.  I already know what I'd like to
see ain't gonna happen.
