[x3d-public] X3DJSAIL: Comments are different in JSON outputs from HelloWorldProgram.java and HelloWorldProgramOutput.java

[Don Brutzman]

Yes they are different and the test cases are exceptional.

Comments contain literal characters.  Literally "whatever."

XML has character entities which allow special characters, for example & is the ampersand character.

X3D SFString and MFString values can have such special characters, but also must escape quotation marks in order to distinguish between a rendered " in X3D dispay or else a simple SF/MFString delimiter.
