For me, semantic + syntax = meaning. Semantic and syntax are two different
fields and togheter make the meaning of a sentence. Your vision makes no
difference between meaning and semantic. So we are using two different notion
of semantic. In few words, for me:
syntax: sequence of words
semantic: meaning of words
The meaning can change if you change semantic (bind) or if you change syntax
(parse or other), but it is not the same thing which you are changing.
