    COMMENT:
    ----------------------------------------------------------------------
    
    I support Murray's DISCUSS.
    
<Nagendra> We will address the DISCUSS comments from Murray.

    I appreciate the fact that "More specifics on the mechanism to characterize
    SF-specific OAM to validate the service offering are outside the scope of this
    document." (§3.1.1)
    
    The issue I want to point out, which I believe is a significant omission in
    this document, is the lack of mention in §4 and §5 of the validation of the
    service offering as an SFC OAM function or in the gap analysis.  IOW, the
    availability of the SF from the point of view of its ability to provide the
    service is pointed out as important in §3.1.1, but there is no further
    consideration later in the document.
    
    [I believe that this issue borders on a DISCUSS -- and while I would really
    like to see further consideration in the text, I decided to trust that the
    authors and the responsible AD will take care of it.]
    
    <Nagendra> I think, this can be addressed by adding the below bullet point in Section 4.1

"Ability to validate the service functionality of an SF."

Please let me know if this address your concern. Please feel free to suggest any text improvement.

Thanks,
Nagendra
