[antlr-interest] Grammar design question

Hi,
I have a question about grammar design that I haven't seen an answer
to in my readings. I may have just not put the pieces together
(sorry!), or it may just not be easily doable.
I have a language where a set of 10 different tokens can occur at a
given point. The tricky part is that some of them can occur multiple
times; some can occur only once; some are optional; and some are
required. On top of that, they can occur in any order. Is it
possible to represent this scenario in an ANTLR grammar?
Thanks,
Reid
