Yes, because an XML *document* may contain more than one external entity.
If XBase passes, it can even happen within the same external entity
in different scopes of the "xml:base" attribute.

No, the risk is that things get treated as the same that are later recognized
as different, either because of the cases above, or because the application
by nature must process more than one document.
