I registered xrdstype.net - but there was never a lot of interest.
If you want to take it over, I think that could be arranged. Its just really a namespace...

Bill, there's never been a formal mechanism for registering service endpoint
types -- since they are URIs, it's inherently decentralized.
http://xrdstype.net/ and the Wikipedia page for XRDS
(http://en.wikipedia.org/wiki/XRDS) are the two "directories" I know of.

What types of additional resource description do you have in mind? Are you
thinking other formats (e.g., RDF, POWDER, XDI)? If so, I think that in the
new XRD design those would just service endpoints with a MediaType (and no
Type) element plus the URI at which that mediatype was available. Example:
<XRD>
<Service>
<MediaType>application/rdf+xml</MediaType>
<URI>http://example.com/some/rdf.xml</URI>
</Service>
</XRD>
As for self-description, we talked about that at the F2F, and no service
type should be needed for that because XRD discovery is recursive, i.e.,
since the XRD is itself a resource with a URI, you can do XRD discovery on
that URI.
For example, if the original URI on which are doing XRD discovery on is
http://yahoo.com, and you discovery the URI of its XRD is
http://yahoo.com/xrd, then to get XRD metadata on the XRD itself, you'd do
XRD discovery on http://yahoo.com/xrd (which might lead you to a URI like
http://yahoo.com/xrd/xrd - whatever template Yahoo uses).
Hope this helps,
