Hey Craig,
rapolicy() hasn't changed in 10 years, so If there is a new syntax, it won't support it, but we can and should add that support, no problem.   If you have pointers for the syntax, I'll take a look.

The way it works, very basically, is that flows are compared to the ACL list, and if there is a match / violation, then it will print out the record.  The comparisons are a bit complicated to account for some of the extended rules, like completion.The rule that applies should (at least based on memory/intent) be added as a label, or it can be printed, if memory serves.  The -v option reverses the logic.

If that doesn't jive, definately send email !!!!
