Done. Will be in the upcoming version.

I would like to keep it simple. If you need to do a test like this, 
you can do it within the rule. You have access both to the list of 
enclosing tags and their attribute hashes.

  table => sub {
    if ($_[1]->{table_number} == 1) {
     ...
    } else {
     ...
    }
  },

Which is also why I include the implementations next to the builtin 
rules in the docs. So that you could easily write a subroutine rule 
that tests whatever you want and then does the same as one of the 
builtin rules.
