Luigi,
Are you trying to import your lexer grammar into your parser grammar? If
so, I don't think that is correct. What you should do to have your
parser grammar use the tokens defined by your lexer is to use the
tokenVocab option, something like this:
grammar ManchesterOWLSyntax;
options {
tokenVocab=ManchesterOWLSyntaxLexer;
}
