Hey team, Looks like when converting to JSON Schema, all the types do not use primitives, but rather refer to an external schema hosted on jsonix.org. Example: ```json { "$ref":"http://www.jsonix.org/jsonschemas/w3c/2001/XMLSchema.jsonschema#/definitions/dateTime" } ``` This site appears to have gone offline, rendering these schemas useless. Wondering: - is this intentional? - are these available on GitHub? Seeking advice
