Is this a new feature, maybe?

Ouch, did we introduce another XML element using an underscore?

Indeed we did. I thought that what we don't like is 'persistent-state' 
but allow 'persistent_state' or 'persistentState'. Do we have preference 
over the two? If so, I can still fix it before it's released.
