I don't think bundling this into the application base class is a good
idea.

I would distinguish the following capabilities:

1. Providing information to the application about entity references. 
This would be appropriate to include XmlAppBase class if it was felt
important enough.

2. Allowing public ids to be mapped to URLs.

3. Allowing URLs to be remapped.

I don't think 2 and 3 should be bundled into the XmlAppBase interface.
Rather they should be provided as a separate XmlEntityManager interface,
because I will often want to use the same XmlEntityManager
implementation with many apps, and I may want to use different
XmlEntityManager implementations with the same app.  The
XmlEntityManager I want depends on how the document is stored, and that
is independent of the document's logical structure which is what will
for the most part drive the application's processing.

For example, I might want to provide an XmlEntityManager implementation
that implements RFC 2110 and allows all the entities of an XML document
to be combined into a single multipart/related MIME body.
