I support this draft.

I'd like to mention about the telemetry attributes from a DOTS server to a DOTS client.
Currently, several transit ISPs are providing DDoS detection and protection services.
In such a service, they send a DDoS detection notification via e-mail when they noticed that their customer is under attack.
The mail includes the telemetry information such as 4.1.5. Attack Details.
This info can be used for further decision of protection strategy by the customer's security operators.
I think it should be covered by the DOTS telemetry specification.

One suggestion to the draft:
Pre-mitigation DOTS Telemetry Attributes can also be signaled from the DOTS server to the DOTS client.

thanks,
Kaname
