Hi Taylor

  As an offerer when I am offering BUNDLE, i will apply IDENTICAL when
offering for those attribute that needs such a behavior.

So yes we need to specify the IDENTICAL on first proposal, also in answer
if the Answerer supports the BUNDLE and the attribute specified and in the
subsequent offer as well if the BUNDLE gets accepted.

Also to note a particular category gets applies internally (in the code)
only after the successful Offer/Answer negotiation.

Hope that helps

Thanks
Suhas
