special characters in xsd element names result in javaStyledNames in mapping

In a XSD-schema file, if xsd elements names include _ . - etc. they will be mapped to javaStyledPropertyNames:
"person.name" would be mapped to: "personName"

Conclusively if you want to convert json data into xml using that mapping, you have to make sure, that the json fields have javaStyledNames otherwise they are ignored.

This

```
{"person":
{"person.name": "honolulu"}
}
```

will end up in empty element:
