AbstractBpmnParseHandler how to parse elements?

[gromar]

My process simulation tool (http://gro-mar.github.io/activiti-crystalball/) is using its own extension for simulation node behavior description.
Process example

    <scriptTask id="scripttask1" name="x = x+1" scriptFormat="groovy" sim:behavior="org.activiti.crystalball.simulator.delegate.PlaybackCopyActivityBehavior">
      <script><![CDATA[x =  x+1
System.out.println( "x is ["+x+"]")]]></script>
    </scriptTask>

v5.11 BPMNParseListener was able to parse such an extension. How can I achieve it with v5.12 AbstractBpmnParseHandler ?

I have found answer here:

It is not supported yet.

Yes indeed, this is due to the new parser we introduced. We will add it shortly again.
