    Hi, Chris:
    If so, let’s adopt them directly then, why seek the opinions from the WG?
    I would like to illustrate my opinions again:
    Application specific attributes just one small part of the application based solution, there are other issues needed to be considered and solved. And I think the alternative systematic  solution will obsolete RFC8919 and RFC8920 together.
    The bis draft are just repeating its precedent, and will be replaced also accordingly, unless it solves the issues that I mentioned.

And what alternate systematic solution are you referring to? The LSR Working Group is not going to defer this update based on some set of hypothetical requirements and solution irrespective of your opinion.
