Btw, the LinkRewriterTransformer is currently only in 2.1.  Although as
the InputModules it depends on are also in 2.0.4, it could be ported
fairly easily.

Yes, it's not an either/or choice.  If a link happens to start with
'site:' (or somesuch prefix) it will be translated.  Pretty much any XML
format can be used, by changing the XPath prefix and suffix.

Just a matter of adding <map:tansform type="xinclude"/> to the pipeline.

Though, the XInclude transformer isn't very good.  XPointer support is
dodgy ('/site/samples' doesn't work, but '/site/samples/*' does), and
there is no support for the xmlns() scheme, meaning if your XML uses
namespaces like Forrest's site.xml, you have to use
*[local-name()='foo'].  You might be better off using XML &entities;.

Requires defining a few input modules in cocoon.xconf and the sitemap.
See CVS Cocoon's linkrewriter block
(http://localhost:8080/cocoon/samples/linkrewriter/).  Actually, wait for
me to commit a fix for the bookdemo sample..
