   From what I read on UML, aggregation is the correct link between map 
and layers since both could exist without being associated to each 
other. But I think the link should be 0..* since a map object could have 
  0 layers.

  As for embedded objects like scalebar, although they could exist 
without a link to a map, they do not really make sense in a general use 
in mapserver (which is to draw a scalebar) without a map object. Not 
also that the map does not need to have a scalebar to be exist. Not sure 
to know what is the best representation, but from my limiyes 
undersanding of UML, aggregational link seems to be the one that defines 
best this relationship.
