I am the assigned int-dir reviewer for this draft. For background on int-dir,
please see the [FAQ](https://wiki.ietf.org/en/group/intdir).

I'm marking this document as "Ready" from an intdir perspective. For someone who is not at all familiar with the topic I found this document to be clear and concise.

While I agree with the points raised in the tsvart review, it is my reading of this document that transport concerns are out of scope of this document and are specified in sibling documents.
