Error: true must be a number

[JoelOnGithub]

When converting XSD schemas with xsd:positiveInteger or xsd:nonNegativeInteger, the converter will throw the error below.

Examples:

  <xsd:simpleType name="N9Type">
    <xsd:restriction base="xsd:nonNegativeInteger">
      <xsd:pattern value="\d{1,9}"/>
    </xsd:restriction>
  </xsd:simpleType>

    <xsd:attribute name="Volgnummer" type="xsd:positiveInteger" use="required"/>

node_modules/xsd2jsonschema/src/visitors/visitor.js:66
                        throw err;
                        ^

I am unsure if I fixed it, or if I just destroyed functionality by changing exclusiveMinimum from true to 0, everywhere in builtInTypeConverter.js.

/* old */
    negativeInteger(node, jsonSchema, xsd) {
        jsonSchema.type = JSON_SCHEMA_TYPES.INTEGER;
        jsonSchema.maximum = 0;
        jsonSchema.exclusiveMinimum = true;
        return true;
    }

/* new */
    negativeInteger(node, jsonSchema, xsd) {
        jsonSchema.type = JSON_SCHEMA_TYPES.INTEGER;
        jsonSchema.maximum = 0;
        jsonSchema.exclusiveMinimum = 0; // Replaced true with 0
        return true;
    }
