Interpreting HERE Maps real-time traffic tags

I've read all the HERE Maps API documentation but couldn't find the answer. What is the meaning of the XML tags in the HERE real-time traffic REST API output?

<FI><TMC PC="4375" DE="Rivonia Road" QD="-" LE="0.55047"/><CF CN="0.83" FF="24.0" JF="6.8228" SP="10.78" SU="10.78" TY="TR"/></FI>

Does anyone know how to interpret this output (I used proximity parameter in my request)?

I noticed that a lot of people have this question and the answer is somewhat difficult to find. I've posted a list of the tag meanings I could find below.

"RWS" - A list of Roadway (RW) items
"RW" = This is the composite item for flow across an entire roadway. A roadway item will be present for each roadway with traffic flow information available
"FIS" = A list of Flow Item (FI) elements
"FI" = A single flow item
"TMC" = An ordered collection of TMC locations
"PC" = Point TMC Location Code
"DE" = Text description of the road
"QD" = Queuing direction. '+' or '-'. Note this is the opposite of the travel direction in the fully qualified ID, For example for location 107+03021 the QD would be '-'
"LE" = Length of the stretch of road. The units are defined in the file header
"CF" = Current Flow. This element contains details about speed and Jam Factor information for the given flow item.
"CN" = Confidence, an indication of how the speed was determined. -1.0 road closed. 1.0=100% 0.7-100% Historical Usually a value between .7 and 1.0
"FF" = The free flow speed on this stretch of road.
"JF" = The number between 0.0 and 10.0 indicating the expected quality of travel. When there is a road closure, the Jam Factor will be 10. As the number approaches 10.0 the quality of travel is getting worse. -1.0 indicates that a Jam Factor could not be calculated
"SP" = Speed (based on UNITS) capped by speed limit
"SU" = Speed (based on UNITS) not capped by speed limit
"TY" = Type information for the given Location Referencing container. This may be freely defined string
