Thanks a lot! Just for the reference of other readers: The following
rule seems to work:

varReference =
(
  hold[attr(0) >> attr("empty") >> uint_]
  | hold[attr(1) >> identifier >> '[' >> uint_ >> ']']
  | hold[attr(2) >> identifier >> attr(0)]
);

where the attribute of varReference is a
boost::tuple<std::size_t, std::string, std::size_t> and identifier
refers to a string consistng of alphanumeric characters and '_' .

Best Regards,
