I do not know where the authors went.  The I2NSF list is not one for 
discussion, rather for fait accompli, a revised I-D appearing along with 
a large PDF that refers to comments and resolution but in a format that 
discourages me from trying to see what has been done and why.  AD 
comments, such as Francesca's, by contrast, are clear and straightforward.

Anyhow, Ira's comment about copying from an RFC caught my eye as this 
YANG pattern, right or wrong, has been replicated in other I2NSF I-D and 
since Francesca has made similar comments about other WG I-D I can see 
that pattern getting copied elsewhere.  I have suggested on the NETMOD 
list that this is one for 6991bis but that I-D has taken a very long 
time to get past WGLC so I suspect that the reaction will not be positive.
