Comment 2 for bug 1564415

We had a good discussion on #openstack-heat-translator IRC meeting March 31, 2016 and can be found in IRC log. Per discussion, current spec of deriving from 'tosca.nodes.SoftwareComponent' is a poor choice for implementation and it's under discussion and to be changed in future version of spec. So no changes in code/definition required for now. We will continue monitoring it.
