The CAVLR3 is an example of an RNAV procedure. A requirement to fly an RNAV procedure is for the aircraft to have navigation equipment capable of finding all of those points. There are many thousands of those waypoints, and it would create way too much clutter to show them all on a chart.
For a pilot planning on flying the CAVLR3, the Enroute H-10 chart can help them find the transition waypoints DORRN, THHMP, and TRSSK. Once they reach a transition, the approach chart covers the remaining route.
If the aircraft does not have the equipment to fly an RNAV approach, they would use a non-RNAV procedure like the COATT4. This follows fixes and VOR's, which are all included on the Enroute L-36 chart.
