Hi, Jason,

Thanks for the feedback, much appreciated. Regarding your first comment below, 
note appendix B,  the first paragraph already says: These examples are not 
intended as recommendations for real-world deployments.
Does this work for you?

Best Regards,
Qiufang

Hi all,

Sorry I've been so slow in getting back to this immutable-flag draft. I've 
finally taken a look at the latest draft (v0.7).

Overall I'm happy with it. My previous comments have been discussed and 
resolved.

Minor comment on A.3 UC3: I think Rob mentioned this previously, but perhaps we 
should say that a hard coded admin account isn't recommended but just used here 
for illustration purposes.

In B.4. change this:
        expect for the "description"
to this:
        except for the "description"

Jason

> 
>    This document defines a way to formally document an existing
>    behavior, implemented by servers in production, on the immutability
>    of some system-provided nodes, using a YANG metadata annotation
>    called "immutable" to flag which nodes are immutable.
> 
>    Clients may use "immutable" annotations provided by the server, to
>    know beforehand why certain otherwise valid configuration requests
>    will cause the server to return an error.
> 
>    The immutable flag is descriptive, documenting an existing behavior,
>    not proscriptive, dictating server behaviors.
> 
>    This document updates RFC 8040 and RFC 8526.
