You can also do your attribute setup (and establish what you need for the
isVirtual test then just call virtualized = pm.PyNode(newNode) and continue
on from there:
@classmethod
def _postCreateVirtual(cls, newNode):
""" This is called before creation, pymel/cmds allowed."""
newNode.addAttr('version',attributeType='double',defaultValue=1.0)
virtualized = pm.PyNode(newNode)
virtualized.customFunction('foobar')
