<div class="">I think trying to figure out the

JSON code is typically executed to create the data structure(s).
In this case it appears that the result will be to put the script
code into a variable that needs to be executed again. Unless JSON
is to be used as another encoding for storage and transport, I
think the use within HTML needs to be settled first.<br class="">

John: let's make the #source content a string array, and then
authors/tools/files can use any of the three forms
equivalently. first 2 out of 3 pass jslint, likely 3 out of 3
just plain work.
<br class="">
<br class="">
as before, but in consistent ["string-array"] form:
<br class="">
<br class="">
- array of one plaintext block string.
<br class="">
- array of one single-line string with all linefeeds and tabs
escaped as \n and \t.
<br class="">
- array of multiple one-line strings as shown below.
<br class="">
<br class="">
A commonly acceptable solution for each of the alternatives
takes all the sting out of any choice, we don't have to worry
about tradeoff advantages/disadvantages.
<br class="">
<br class="">
Pretty exciting that a no-lose approach might exist to cope with
this situation! 8)
<br class="">
<br class="">
So I will change stylesheet support for the three alternatives
to all be string _array_ and rebuild the examples.
<br class="">
<br class="">
I hope this fine tuning doesn't interrupt your loader efforts.
<br class="">
<br class="">
p.s. cosmetic: maybe we should rename #source to #sourceText or
somesuch - a more descriptive key name might also be preferable.

glad to hear it!

If arrays of json strings are typical and acceptable and not
an undue complication for plain old javascript programmers,
then it is certainly fine with me. I strongly believe that
human readability is important. Quoted strings are surely
better than garble.

It is no trouble for me to export .x3d to .json #source that
way as well. I have added another option to the stylesheet
switch tonight to produce that alternative.

Example attached, excerpt follows. Hmmm, not too bad, and
certainly not confusable.

I will again regenerate all examples in that form if opinions
are leaning that way.
