[x3d-public] Using draft 07 with latest Ajv2019 classes.

[John Carlson]

The new version 8 of ajv appears to support draft 07 by adding a schema 
to Ajv2019 class instance, but I tried with the Ajv class instance, and 
it didn't work.

https://ajv.js.org/guide/schema-language.html

describes how to use draft07 with Ajv2019.

So if anyone wants to attempt to use draft 07 with the latest Ajv, that 
would be cool.

The main problem appears to be "uri"

Here are the changed I tried:


~/x3dvalidate$ git diff .
diff --git a/index.js b/index.js

Thanks,
