Hello Mike, thanks for the comments.
I fully understand your concerns.

Here is our plan.

Any duplicate parts will be removed.
Only a couple of sentences, regarding the philosophy of the stateless fair
queuing, will remain in 6.1 Framework.
Without the consideration for readers' ease of understanding, we will just
refer to the ITU-T standards.
The readers should open up the ITU-T standards for complete understanding
of the technology.

However, the metadata enhancement (two instead of three) will be stated, as
an option, with clearly stating that this is a deviation from ITU-T
standards.
Of course, the original three metadata can be also carried by default.

If this plan suits your requirements, please let me know.
We will gladly revise accordingly.

Best regards,
Jinoo (on behalf of authors)
