-# IDL Node
-#
-# IDL Node defines the IDLAttribute and IDLNode objects which are constructed
-# by the parser as it processes the various 'productions'.  The IDLAttribute
-# objects are assigned to the IDLNode's property dictionary instead of being
-# applied as children of The IDLNodes, so they do not exist in the final tree.
-# The AST of IDLNodes is the output from the parsing state and will be used
-# as the source data by the various generators.
