That is a very important point.  And that is why the semantics should be
defined in a way that is independent of any specific notation,  graphic
or linear.    (02)

And the notation-independent semantics should be designed in such a way
that it can be easily mapped to any format that anybody might prefer
for any purpose whatever.    (03)

In particular, I strongly recommend controlled natural language (CNL)
as a notation for logic that can be automatically translated to a
spoken form.    (04)
