I found one small thing in this concise draft.  In the list of configuration information in Section 5:

OLD
   o  IPv4 Type of Service or IPv6 Traffic Class Fields.
NEW
   o  DSCP Field in either IPv4 Type of Service or IPv6 Traffic Class Fields.

That may raise the question of what to do with the remainder of those two fields, which is the ECN field.  RFC 7510 does not specify what to do, so just clear the ECN field to 00b, which indicates that ECN is not supported.

Thanks, --David
