[x3d-public] renewed development of X3D JSON support

[Brutzman, Donald (Don) (CIV)]

Regular expressions are icing on top of the gravy and an extra independent layer of validation checking string patterns for simple types (well-formed floats etc.) so not necessary for most element/attribute evaluation.

All of the detail is in the schema, meanwhile HelloWorld.json is almost certainly correct given all the torment it has received.

We can report issues to (a) Altova or (b) AJV if you think it worthwhile.

I’d press on.  It is always interesting to see how other tools work.

all the best, Don

I've put the converted schema through the Ajv 8 validator. Here's what
I've gotten so far, with HelloWorld.json.  I don't know if the problem
stems from Ajv or the schema, or the HelloWorld.json.  One reason why I
had to take out pattern match was the XML Schema regular expressions
were not the same as the JavaScript regular expressions.  I'm not sure
how portable regular expressions are between encodings, in other words.
Any I don't really know what XMLSpy has done.  Maybe check documentation
about regexps on Altova's website.
