[TxMt] Re: including rules from another language's repository

I am working on a language grammar. I would like to include repository rules from a different language. I have tried including the language itself at the top of my grammar and then including the rule in necessary place in my grammar but it does not appear to work. I am hoping that there is a syntax for doing this and I just haven't discovered it yet. If anyone can point me in the right direction I would appreciate it!

In case anyone else is wondering about this, I eventually answered my own question. This is possible in TM2 using grammar#repo_rule like this:

{ include = 'source.objc#interface_innards'; },
