I agree - good catch.

Yes - I missed these when addressing Med's comment. Will fix.

At first I didn't agree with this but I see this constraint for the sub-TLVs 
containing
extended-admin groups in RFC 9350:

   The IS-IS FAEAG sub-TLV MUST NOT appear more than once in a single
   IS-IS FAD sub-TLV. If it appears more than once, the IS-IS FAD sub-TLV
   MUST be ignored by the receiver.

Hence, we are in agreement that this is the reason for using a YANG leaf rather
than a leaf-list (not the fact that te-type:extended-admin-group maps to a 
hex-string). 

Right? 

Thanks,
Acee
