[X3D-Public] Any way to get 'this' proto instance inside itself?

What I ended up doing was adding

inputOutput SFNode thisInstance NULL

to the proto def, and all instances must reference itself:

DEF p1 myproto { thisInstance USE p1 }

If there's a better way, I'd like to hear it. If not, would like to 
request it as a feature for next go-around.
