That is not quite accurate.

Any time you redefine attributes using node[...] or edge[...], they  
stay in force as defaults for nodes and edges defined afterwards.

I make very heavy use of this to keep diagrams from being cluttered  
with lots of decoration. There's an example file in this style and

I agree it would be nice to have a way to use something like CSS  
classes to associate a style with a node defined in an arbitrary  
location.
