Hi Acee,

I think the motivation below makes sense. Actually this is the way people had already been doing, not only operators.

"One major benefit of using administrative tags rather
   than IANA defined TLVs or sub-TLVs to indicate different services is
   to facilitate the rapid deployment of new services without any need
   for the standardization of those TLVs or sub-TLVs.  However, there
   are some special use cases where the service to be advertised has one
   or more attributes which need to be advertised as well.  In such
   case, the administrative tag is not much applicable anymore"

Personally I wish one more generalized mechanism can exist instead of one Node tag and one proprietary TLV.
Anyway, I'd like to see this I-D can go further and "lot of things we can further improve" at the same time, as Uma mentioned.
