I second the idea of exploring the use of URI Templates for
documenting how to construct a URL from other data. I'm not sure if
it's part of the latest URI Templates draft [1], but OpenSearch allows
parameter names to be defined with namespaces [2]. For example:

 <?xml version="1.0" encoding="UTF-8"?>
 <OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/"

   <Url type="application/vnd.google-earth.kml+xml"

Note, the use of the geo namespace and the geo:box parameter name? So
you could imagine a URL template that referenced names from an RDF

<Url type="application/rdf+xml"
template="http://example.com/user/{foaf:mbox_sha1sum}" />

OpenSearch was an incubator for the ideas that led to the URI
Templates draft, and is built into many modern web browsers (IE,
Firefox, Chrome).
