Hello,


I understand that an attribute grammar provides a static semantics of
a given context-free grammar.


However, I am wondering in general how one determines inherited
attributes and synthesized attributes for terminals and nonterminals
of a given context-free grammar.


Is there a rule that tells how those attributes should be determined
or the determination should be done so that those attributes reflect
the semantics of the grammar (so, could be arbitrarily defined)?


I would really apperciate any explanation and pointers that I could
find more information about the subject.


Thank you very much for your time.


Regards,
Seongbin Park
