JSON-Schema generated from XSD does not use maxLength

After using the Maven plugin for generating a JSON-Schema from an XSD (which is included in a WSDL), I notice that the maximum length restrictions are not reflected in the JSON-Schema.

Here is a simplified and cut version of my XSD:

```

```

The `maxLength` is not represented in the generated JSON-Schema. This is unfortunate, as I want to pass on the JSON-Schema to other parties as a technical documentation, and tell them that if their JSON validates with the schema, it's good for me to accept.

Is there any good way how I can have the JSON-Schema generated with `maxLength`?
