Section 4.4.2 says:

   Percent_LossRatio:  The numeric value of the result is expressed in
      units of lost packets to total packets times 100%, as a positive
      value of type decimal64 with fraction digits = 9 (see Section 9.3
      of [RFC6020]) with a resolution of 0.0000000001.


It should say:

   Percent_LossRatio:  The numeric value of the result is expressed in
      units of lost packets to total packets times 100%, as a positive
      value of type decimal64 with fraction digits = 9 (see Section 9.3
      of [RFC6020]) with a resolution of 0.000000001.


Notes:

An extra 0 in the value of the resolution of the loss ratio.

The error is repeated in sections 7.4.2.6, 8.4.2.6, 9.4.2.4

Section 5.3.5 says:

5.3.5.  Runtime Parameters and Data Format

   Src:  The IP address of the host in the Src Role (format
      ipv4-address-no-zone value for IPv4 or ipv6-address-no-zone value
      for IPv6; see Section 4 of [RFC6991]).

It should say:

5.3.5.  Runtime Parameters and Data Format

   Runtime Parameters are input factors that must be determined,
   configured into the measurement system, and reported with the results
   for the context to be complete.

   Src:  The IP address of the host in the Src Role (format
      ipv4-address-no-zone value for IPv4 or ipv6-address-no-zone value
      for IPv6; see Section 4 of [RFC6991]).

Section 10.1.4 says:

   RTLoss:  This metric assesses the estimated loss count for TCP
      packets constituting a single connection, exchanged between two
      hosts.  We consider the measurement of round-trip delay based on a
      single OP [RFC7011] somewhere in the network.  The output is the
      estimated loss count for the measurement interval.

Notes:

This is where loss count is measured, not round-trip delay.
--VERIFIER NOTES--
From Al Morton: Sorry, but the original text is correct. In this case we have a RT loss *estimate* conducted in the context of (and using the same packets as) the RT Delay measurements described for TCP. We considered this text carefully before publication.
