Hi Mahesh,

I'm okay not adding the ability to reference an external rulebase now, or are you saying that you'd also like to defer priming the YANG model now so that it can be added later in a backwards compatible manner?

If you plan to prime the YANG model so that the ability to reference an external rulebase can added later in a backwards compatible manner, can you please send a concrete proposal to the list so that we can better understand the impact?  

My expectation is that it merely adds a 'choice' statement around the existing rulebase container, thereby enabling something other than a rulebase container to exist some day in the future.  

If the addition is indeed just this, then I don't believe that it materially changes the ACL model and therefore can be added as a LC comment.  Of course, the WG will want to review the addition for correctness, but otherwise should be alright.

Thanks,
Kent // co-chair and shepherd


===== original message =====

Kent,

I have not heard a strong requirement to have the open issue fixed in this version of the RFC. We would therefore like to defer it to a bis document.

I will wait for the LC to complete, and update the draft to address all the comments received during the LC.

Thanks.
