I'm not sure I understand this, but it looks as if you want to keep the
abstract syntax the same and change the mapping rules.  This is going to be
difficult at best, as Jeremy's abstract syntax has some significant (I
would even call them fundamental) differences from the abstract syntax in
S&AS.   I will be preparing a document this morning on some of the
differences.

Actually all three of these would have consequences for the rest of S&AS.

I would call it somewhat closer to S&AS.
