How to generate empty String values, " " using wsdlOptions for artifacts in CXF ?

Issue

• We are migration IBM Web integrations to Fuse integrations.
  In the IBM Web product it is possible in a Web Service response to add empty mandatory xml elements if they are not set, eg:

<beskrivning></beskrivning>

• In Fuse we are using wsdl2java maven plugin to generate the Java code. Se the plugin example in attached pom file.
  Code generated with the plugin wsdl2java typically looks like this;
  This xsd definition:

<xsd:element minOccurs="1" name="beskrivning" type="xsd:string" ></xsd:element>

Generates this java code:

@XmlElement(required = true)
    protected String beskrivning;

  public String getBeskrivning() {
        return beskrivning;
    }

    public void setBeskrivning(String value) {
        this.beskrivning = value;
    }

Is it possible to use a wsdlOption or plugin for fields that are mandatory and of type String to generate getters that returns a default value of "".

Like this:

 public String getBeskrivning() {
         if(beskrivning == null){
              return "";
        }
        return beskrivning;
    }

Is there a way to accomplish this with wsdl2java?
We know that the best solution would be to fix the schemas to have minOccurs="0", but that is not possible right know.
