I interpreted the use of the term "pruned" as being, well, like not 
there anymore, or after parsing, evermore. It got clipped off and 
never got to make a bud (node).
Hidden stuff is rejected up front, I was thinking.
So, a player in a @hidden element that was "pruned" would not be 
there, so no problem.
But I am still not understanding or missed a use case for this. .
Thank You and Best Regards,
Joe
