Section 5.10.2.1 says:

   QoS classification rules are handled by "qos-classification-policy".
   qos-classification-policy is an ordered list of rules that match a
   flow or application and set the appropriate target CoS
   (target-class-id).  The user can define the match using a
   more specific flow definition (based on Layer 2 source and
   destination MAC addresses, cos, dscp, cos-id, color-id, etc.).  A
   "color-id" will be assigned to a service frame to identify its QoS
   profile conformance.  A service frame is "green" if it is conformant
   with the "committed" rate of the bandwidth profile.  A service frame
   is "yellow" if it exceeds the "committed" rate but is conformant with
   the "excess" rate of the bandwidth profile.  Finally, a service frame
   is "red" if it is conformant with neither the "committed" rate nor
   the "excess" rate of the bandwidth profile.

It should say:

   QoS classification rules are handled by "qos-classification-policy".
   qos-classification-policy is an ordered list of rules that match a
   flow or application and set the appropriate target CoS
   (target-class-id).  The user can define the match using a
   more specific flow definition (based on Layer 2 source and
   destination MAC addresses, dscp, color-type, etc.).  A
   "color-type" will be assigned to a service frame to identify its QoS
   profile conformance.  A service frame is "green" if it is conformant
   with the "committed" rate of the bandwidth profile.  A service frame
   is "yellow" if it exceeds the "committed" rate but is conformant with
   the "excess" rate of the bandwidth profile.  Finally, a service frame
   is "red" if it is conformant with neither the "committed" rate nor
   the "excess" rate of the bandwidth profile.

Notes:

There is no "color-id" under "qos-classification-policy". The text should refer to "color-type" given that the "qos-classification-policy" substree is as follows:

+--rw service
| +--rw qos {qos}?
| | +--rw qos-classification-policy
| | | +--rw rule* [id]
| | | +--rw id string
| | | +--rw (match-type)?
| | | | +--:(match-flow)
| | | | | +--rw match-flow
| | | | | +--rw dscp? inet:dscp
| | | | | +--rw dot1q? uint16
| | | | | +--rw pcp? uint8
| | | | | +--rw src-mac? yang:mac-address
| | | | | +--rw dst-mac? yang:mac-address
| | | | | +--rw color-type? identityref
| | | | | +--rw target-sites*
| | | | | | svc-id {target-sites}?
| | | | | +--rw any? empty
| | | | | +--rw vpn-id? svc-id
| | | | +--:(match-application)
| | | | +--rw match-application? identityref
| | | +--rw target-class-id? string

The same applies for "cos" and "cos-id".

The corrected text uses "color-type" instead of "color-id" and removes "cos" and "cos-id" from the flow definition examples.
