Cosmas II grammars are written in Antlr 3 language which is quite different from Antlr 4. The tree outputs would probably also be different.

Other QLs (Poliqarp, Annis, FCSQL) use Antlr 4. Thus, we use both Antlr 3 and 4 libraries, which fortunately do not conflicted with each other.

This may be of interest for Franck, as he wrote the C2-grammar, if I am correct.
