xsd:elements defined under a xsd:choice should be correctly represented in the java class

Given an xsd sample:
```xsd















```

This generates a class with setters for each property. That means, we can initialize multiple fields in once object instance of Data. This should be restricted. Ideally, it should have maybe create multiple constructors which accepts only one field.
Like:
```
public Data(Null null-data)
{this.null-data=null-data;}
public Data(SeqeunceOfData array)
{this.array=array;}
```

These constructors created for each field would have the correct representation and restricts user to only initialize the Data object with one field.
