XML attributes will probably have relative URLs in them and the XML
Application will have to know how to resolve them. Tim is right that
attributes are syntactically checked when they are created and can throw
an exception if there is a mistake. I would rather leave that up to the
application writer.

XML mandates URIs, but Java supports URLs. I don't think that all Java
environments will allow new URL types to be installed. But if we are
just passing around strings then the application can recognize URNs and
Do The Right Thing.

I think that all we are doing is shifting the "new URL(String)" calls
from the processor to the application.
