RDDL and XML Catalogs can work well together.

RDDL _describes_ a namespace via text and a collection of resources
The way one gets a RDDL document from a namespace URI depends on the URI resolution process.
For example:
<foo xmlns="urn:publicid:-//FOO//Bar Version 1.0//EN">
</foo>
Software might use this URN based namespace
to find the location of the RDDL document in the supplied
XML Catalog.
