[Laszlo-user] Setting the parent of a tag

[P T Withington]

The placement attribute is the name of a subnode, not a node object  
(and that if the named node cannot be found, the placement reverts to  
default lexical placement).  If you want to do something more  
sophisticated, you need to override the determinePlacement method.

inheritance.html#d0e17794
