[x3d-public] addChildren and removeChildren

[cbullard at hiwaay.net]

addChildren and removeChildren:  is it the case that removeChildren  
cannot be used to remove
a child that was added by addChidren because a script cannot get a  
reference to a node added
using addChildren?

Examples of these functions are sparse at best online and those are a  
few decades old.   I
find I can add a node.  I can remove a node but the removed node must  
be current in the
scenc graph at load time.

Any one able to commment, much appreciated.
