Now of course if you have two different attributes of type ENTITY referring to unparsed entities with the same notation, or two different attributes of type NOTATION with the same value, or one of each, then you need to extend the convention further. Nevertheless, it *can* be done. The effective attribute tree gets flattened into an attribute space, with the tree information stored in the attribute names. > You can only specify one notation per element > instance (which might be a design bug now that I think about it--I can > thing of cases where the same element might be reasonably governed by > different notations relevant to different processing domains).
