What if a single resource needs description resources that are
consumed by different applications, but there is no way to combine the
two DRs into one document, and they cannot be distinguished by media
type?
Not a problem if the DRs use RDF, but you are not limiting DRs to RDF.
Registering a new media type for each application is not practical.
Perhaps you could parameterize DRD by the link relation - that is,
where you now say "describedby", put a variable that takes on a
different value for each application. Then you could use one link
relation for A (POWDER) and another for B (XRD).
The link-extension feature of Link: (and link-pattern?) might also
help here, although I'm not sure how that would work with <link>.

For those who have read previous revisions (thanks!), please note
that except for Appendix B, the rest of the spec was significantly
changed and a fresh read is recommended.
Thanks,

Title : Link-based Resource Descriptor Discovery
Author(s) : E. Hammer-Lahav
Filename : draft-hammer-discovery-02.txt
Pages : 25
Date : 2009-02-12
This memo describes a process for obtaining information about a
resource identified by a URI. The 'information about a resource', a
resource descriptor, provides machine-readable information that aims
to increase interoperability and enhance the interaction with the
resource. This memo only defines the process for locating and
obtaining the descriptor, but leaves the descriptor format and its
interpretation out of scope.
