well the spec's not over clear but that's my reading (and I think it's 
what existing parsers do). For external parsed entities, if you want to 
simply inline, you can (sometimes) make use of xml:base to locally reset 
the base URI, but for the examples you gave of parameter entities in a 
DTD I don't think there is any local scoping construct that you could 
use with xml:base, so you need to keep track of the scope of the inclusion.
