John, as it turns out, the set_ prefix and _changed suffix are only
optional when connecting to accessType inputOutput fields. They are
required for a large number of output_only and inputOnly fields
(respectively).
>From what I can see in
http://www.web3d.org/documents/specifications/19775-1/V3.3/Part01/concepts.
html#FieldSemantics
the set_ and _changed adornments are _recommended_ , presumably for reasons
of better readability. Since these did not seem to be required, browser
makers had to allow for both options, pure and adorned. Can you clarify
your argument for a strict requirement ?
Andreas
I have improved the tooltips regarding this matter, hopefully adding
clarity.
I fixed the prior X3DJSAIL code problem when testing accessType and type,
hopefully it is better aligned now. Deployed last night. Will test further
special cases in the future.
Improved tooltips are also posted:
X3D Tooltips: ROUTE
http://www.web3d.org/x3d/content/X3dTooltips.html#ROUTE
==================================
[fromField type NMTOKEN #REQUIRED]
fromField is the field name in the source node which is originating an
event.
Hint: if (and only if) corresponding field has accessType inputOutput,
author has option to append "_changed" suffix to field name - both forms
are functionally equivalent.
Warning: if corresponding field has accessType outputOnly or inputOnly, do
not modify the set_ prefix or the _changed suffix on the field name.

==================================
[toField type NMTOKEN #REQUIRED]
toField is the field name in the destination node which is receiving an
event.
Hint: if (and only if) corresponding field has accessType inputOutput,
author has option to prepend "set_" prefix to field name - both forms are
functionally equivalent.
Warning: if corresponding field has accessType outputOnly or inputOnly, do
not modify the set_ prefix or the _changed suffix on the field name.

==================================
Hopefully this prose is clear. Improvements or question/clarifications or
hints/warnings are always welcome.
Updated version of your example attached with set_ and _changed inserted.
It now compiles and runs.
corrected exerpt:
.addChild(new ROUTEObject().setFromNode("TourTime").setFromField("
cycleTime").setToNode("RandomTourTime").setToField("cycle"))
.addChild(new ROUTEObject().setFromNode("RandomTourTime").setFromField(
"orientation").setToNode("TourOrientation").setToField("keyValue"))
.addChild(new ROUTEObject().setFromNode("RandomTourTime").setFromField(
"position").setToNode("TourPosition").setToField("keyValue"))
.addChild(new ROUTEObject().setFromNode("TourTime").setFromField("
fraction_changed").setToNode("TourOrientation").setToField("set_fraction"))
.addChild(new ROUTEObject().setFromNode("TourOrientation").
setFromField("value_changed").setToNode("Tour").setToField("orientation"))
.addChild(new ROUTEObject().setFromNode("TourTime").setFromField("
fraction_changed").setToNode("TourPosition").setToField("set_fraction"))
.addChild(new ROUTEObject().setFromNode("TourPosition").setFromField("
value_changed").setToNode("Tour").setToField("position"))) ;

access are collectively referred to as output fields, and the events these
fields receive and send are called input events and output events,

sources, in precedence order, shall be used to determine the initial value

which runs, so I can look at it and get my java serializer working. I will
soon download X3dToJava.xslt, and play with it. I guess you want me to
test it too? ? or instead? LOL! Not everyone wants to run a stylesheet.
I?ve been doing it because I don?t have a good XML to X3D JSON converter
yet ?. Let?s break the monopoly! This was my start of one:
https://github.com/coderextreme/X3DJSONLD/blob/master/Standard.js Let?s
just say generating X3DJSON is hard. I was even able to generate JSON for
the three-x3d-loader. The code is found here: https://github.com/
coderextreme/X3DJSONLD/blob/master/Three2Serializer.js so you might base
it on that. IDK, working with X3DJSON as a source seems easy enough.
