How about this:

http://www.loc.gov/zing/srw/dcx/

The schema text behind this URI should be:

DCX stands for Dublin Core eXtended. DCX means that the XML records are
encoding according to the DCMI guidelines and contain terms from the dc and
dcterms namespaces. The records may contain terms from other namespaces
when they could not - within reason - be expressed by terms from the dc and
dcterms namespaces. It is recommended that as much as possible terms from
DCMI registered elementsets are being used.
DCX may be used as an alternative for the actual name of a schema or a  DC
Application Profile to allow for requesting or providing records for which the
name is not known to the requestor but which can safely be used by the requestor
for extracting terms that are defined in the Dublin Core registry.
