one more discussion topic: perhaps the "validate" name is too general? 
Maybe we can come up with more descriptive name? There are all kinds of 
nodes and sometimes this name can be misleading (not ringing the layout 
bell at all). For example TextField.validate() may look like validating 
the input. Also I wouldn't be surprised if users run into problems with 
custom nodes having their "validate" methods for different purposes.
