I realized that the "universal semantics" attached to a derivation
with respect to a grammar that I asked for is just the parse tree, as
if one preserves just the way the action functions are combined,
throwing away the functions themselves, there remains only a graph
which is just the parse tree.
In other words, grammars with a universal semantics is already studied in
the form of parse trees. It is an interesting viewpoint of language theory
that seems to somewhat hidden in the books I have looked into.
