> +: A variable-length integer encoding the intentional delay between when the
+ largest acknowledged packet, as indicated in the Largest Acknowledged field,
+ was received, and when the ACK frame was sent; see {{host-delay}}.
+ The acknowledgement delay in microseconds is the value of the ACK Delay
+ field multiplied by 2 to the power of the ack_delay_exponent transport
+ parameter sent by the sender of the ACK frame;
+ see {{transport-parameter-definitions}}. Scaling in this fashion allows for
+ a larger range of values with a shorter encoding at the cost of lower
+ resolution. Because the receiver doesn't use the ACK Delay for Initial and
+ Handshake packets, a sender SHOULD send a value of 0.
That last bit won't format correctly. You need a ': ' at the start of the line, or maybe we could move it elsewhere.
